Question

What number should be added to −4/5 to get −3/8 ?
step by step instructions ​

Answer 1

Step-by-step explanation:

First let's get their denominators to the same.

-4/5 = -32/40

-3/8 = -15/40

Secondly, let's find their difference.

-32/40 - -15/40 = -17/40

So, by adding 17/40 to -4/5, we'll get-3/8.

Answer 2

Answer:

Suppose, the number should be added is x

to get,

-4/5 + x = -3/8

x = 4/5 - 3/8

x = 32-15 /40

x = 17/40

Let's check,

= -4/5 + 17/40

= -32+17 /40

= -15/40

= -3/8

Hence the number is = 17/40
