Question

7. Meghraj divided like this. 1.05 2.1 → 105 210 Do you agree with what he did? Explain your thinking.​

Answer 1

Explanation:

I guess that means

1.05 / 2.1

or

1.05 ÷ 2.1

both mean the same thing.

so, let's look at

1.05 / 2.1

this is the same as

105/100 / 210/100 = (105×100) / (210×100) =

= (105×100) / (210×100) × (1/100 / 1/100)

as long as we multiply numerator (top) and denominator (bottom) always with the same thing, the general fraction or division is unchanged.

(105×100) / (210×100) × (1/100 / 1/100) =

= (105 × 100/100) / (210 × 100/100) = 105 / 210

so, yes, the division of 105 / 210 is the same as 1.05 / 2.1
