Step-by-step explanation:

Given:

Hashim had some money.

His sister had $75.10.

After Hashim gave his mother $28, he had $15.20 less than his sister.

Solve for:

The original amount of money Hashim had.

Step 1: Define the problem

Let's say, Hashim had an original amount of money, we call it A

Hashim gave his mother 28$, then his remaining amount of money is A - 28

Hashim's remaining amount of money is 15.2$ less than his sister's amount of money: 75.10$.

Hence, the relation between Hashim's remaining amount of money and his sister's amount of money is expressed as:

A - 28 = 75.1 - 15.2

Step 2: Solve the equation to get A

A - 28 = 75.1 - 15.2

Let's first perform the subtraction on the right side of equation:

A - 28 = 59.9

Now, we move all of numbers to the right side of equation, except A:

(please notice that the sign of 28 will be changed from - to +)

A = 59.9 + 28

Let's perform the addition on the right side of equation to get A:

A = 87.9$

=> Hashim's original amount of money: A = 87.9$

Hope this helps!

36/2=18

60/2=30

18/30

18/3=6

30/3=10

6/10

6/2=3

10/2=5

your final answer would be 3/5 of an

hope this !
