There is a number after the decimal point in each factor. So, there will be two numbers after the decimal point in the product.

Therefore, the answer is 0.75

$2.5 \times 0.3 = 0.75$

There is a number after the decimal point in each factor. So, there will be two numbers after the decimal point in the product.

Therefore, the answer is 4.03

$3.1 × 1.3 = 4.03$

(d) 0.35 ÷ 0.5

= 35 ÷ 5

100 10

= 35 × 10 ( Reciprocal)

100 5

( Fig 1.1 )

So, we get the answer as 7 which is 0.7.

10

Therefore, the answer is 0.7

0.35 ÷ 0.5 = 0.7
