Question

Reduce 75 litres of water by 15%

Answer 1

63.75 litres

Explanation:

the original amount of water is 100%

then a reduction of 15% = 100% - 15% = 85% of original

multiply 75 litres by 85% to obtain reduction

75 × 85%

= 75 ×
`(85)/(100)` = 75 × 0.85 = 63.75

75 litres reduced by 15% = 63.75 litres
