Question

2/5 ×(-3/7)=
please do it fast ​

Answer 1

Answer:

First convert both fractions to equivalent fractions (fractions with same denominator) by taking the Least Common Multiple (L.C.M) of the denominators.

Here LCM of 5 and 7 is 35 (since LCM of Coprimes is their product).

Now to get the equivalent fraction, take the first fraction 2/5.

Think how many times the denominator will give you 35. It's 7. So mutiply numerator and denominator by 7. So we get,

(2×7)/(5×7) = 14/35

Similarly,

(3×5)/(7×5) = 15/35

We got equivalent fractions.

Now subtract the equivalent fractions.

14/35 - 15/35 = (14–15)/35

[ Since the denominators are same, we can directly add the numerators to get the result. This is the purpose of finding equivalent fractions].

= -1/35

= -0.02857 is your required answer.
