Hint

Add up the light grey columns.

Hint

Compare the heights of the dark grey columns.

Hint

When you multiply a number by ten you add a nought to the right. Example: 21 x 10 = 210

Here’s an exception – when there’s a decimal point.  21.5 x 10 = 215.0 NOT 21.50

Hint

You’ll need to work out A before you can work out C.
To work out A, use A x 9 = 63. Use your 9 times table, or divide 63 by 9.

Hint

Use a piece of paper, don’t try to do this in your head.
Start by finding the combined height of the other two mountains.

Hint

Numbers on the left are 1,000 less than those on the same row on the right.
The comma is placed just after the thousands digit. Example, 3,500 is three thousand five hundred.

Hint

The numbers that start with a zero are smaller than those that start with a 1; that should narrow down the choice.

Hint

There are 12 months in a year; 24 hours in a day; 7 days in a week.

Hint

The decrease in the number of cars in stock is the number of cars sold take away the number of cars delivered. Subtract this decrease from the number in stock at the start.

Hint

If a shape has 34 shaded, the number of shaded areas in the shape equals the total number of areas times three quarters.

Hint

When you round a number, the answer could be higher or it could be lower.

Hint

The question asks for the answer in minutes, so there is no need to convert to hours and minutes.

Remember, 1kg means 1 kilogram

Hint

Remember that the 100 minutes cooking time includes 40 minutes which is always added in, so start by taking that away to see what’s left.

Hint

Vertices are the points where two or more lines meet. In other words, a corner.

Hint

To work out what 12 stickers cost is hard because 12 x 0.99 is not a nice multiplication. But you could do 12 x 1 and then subtract 12 pence (one penny per sticker).

Hint

We know that 12 seeds grew. The number she planted must be more than 12, as some did not grow. How many more? The ratio of seeds planted to seeds that grow is 3:2

Hint

‘Figures’ means digits, for example 2017. Do not write your answer out in words, like ‘two thousand and seventeen’.
And for some weird reason, we don’t use a comma in years. So you would not write 2,017 for the year 2017.

Hint

Hint

In coordinate pairs, the x-axis value is first, followed by the y-axis value.

Hint

A full day (100%) = 24 hours
A half day (50%) = 12 hours
A quarter of a day (25%) = 6 hours

Hint

To find out what she spent on posting 3 letters, take away what she has left from the amount she started with. Then you can divide that by three to work out what each letter costs to post.

Hint

To solve this, Adam would have converted the amounts so they are in the same format, either both decimals or both fractions, to allow them to be compared.

Hint

One centimetre on the map is 20km; two centimetres is 40km, and so on right up to 250km.

Hint

As the two triangles are similar, the ratio of side a to side b is the same as the ratio of the heights of the two triangles. These are easier to compare.

Hint

For the diagram you can see that one quarter plus two sixths remain unshaded. Two sixths is the same as one third. To add up 1/4 + 1/3 you need to find a common denominator. One way to do this is to multiply the denominators together. 4 x 3 = 12.

So 12 is a common denominator. Now you can convert each part to twelfths. How many twelfths is one quarter? How many twelfths is one-third?
