Example 1
Write in the missing number.
79.5 × ________ = 773.9
Answer
On your calculator, work out the inverse, which is
773.9 ÷ 79.5 = 9.73459119496
So, we write
79.5 × 9.73459119496 = 773.9
Example 2
Work out
45% of 3404
45% is 45/100 which is 0.45 as a decimal.
So, on the calculator, we work out
0.45 × 3404 = 1531.8
