Question

Find
a)150% of 40 kg
b)9 is 25% of what number​

Answer 1

Answer:

Step-by-step explanation:

a)150% of 40kg

= $\frac{150}{100}$ of 40kg

15 x 4 = 60kg

∴150% of 40kg = 60kg

b)9 is 25% of what number

Let the number be x

25% of x = 9

$\frac{25}{100}$ of x = 9

$\frac{1x}{4}$ = 9

x = 36

∴9 is 25% of 36
