Question

Find the product:
(i) 35.853 × 100
(ii) 42.5 × 100
(iii) 12.075 × 100
(iv) 100 × 0.005

Answer 1

i) On dividing by 1,000, we get:

$\frac{35853}{1000}\times 100=\frac{35853}{10}=3585.3$

ii) On dividing by 10, we get:

$\frac{425}{10}\times 100=425\times 10=4250$

iii) On dividing by 1,000, we get:

$\frac{12075}{1000}\times 100=\frac{12075}{10}=1207.5$

iv) On dividing by 1,000, we get:

$100\times \frac{5}{1000}=\frac{5}{10}=0.5$
