Question

the product of two numbers is -21/8 .if one number is 7/5 then find the other number.
​

Answer 1

Answer:

-21/8 × X=7/5

then, X=7×8/5×(-21)

=8/(-15)

=(-8/15)

Answer 2

Given,

The product of two numbers = -21/8

One number = 7/5

To find,

The second number of the product.

Solution,

The other number in the product is -15/8.

We can easily solve this problem by following the given steps.

Now, let's take the other number to be x.

The product of two numbers = -21/8

(7/5) × x = -21/8

7x/5 = -21/8

7x = -21×5/8 ( 5 was in divide on the left-hand side. So, on the right-hand side, it is in multiplication)

x = -21×5/8×7 ( 7 was in multiplication on the left-hand side. So, on the right-hand side, it is in divide.)

x = -3×5/8 (Dividing 21 in the numerator by 7)

x = -15/8

Hence, the other number will be -15/8.
