Question

2.1/0.7=3 but how do you work it out (I cheated and used a calculator)

Answer 1

Answer: To work out 2.1/0.7 without a calculator, you can use long division as follows:

0.7 | 2.1

1.4 (3 times 0.7 is 2.1)

-----

0.7

0.0 (there is no remainder)

Therefore, 2.1/0.7 = 3, which means that 2.1 is equal to 3 times 0.7.

Answer 2

see below

Explanation:

2.1

-----

.7

Multiply the top and bottom by 10 to get rid of the decimals.

2.1 *10 = 21

.7 * 10 = 7

21/7 = 3
