of Mahmud's money. They have $756 altogether. How much does Mahmud have now?
Call the amount that Mahmud has X
And call the amount that Rihan has is 4 • 1/5 • X
Together, they have 756
Add M's & R's together to equal X + ( 4 • 1/5 • X ) = 756
4 • 1/5 • X = 4X/5
1 • X = 5X/5
4X/5 + 5X/5 = 9X/5 = 756
Multiply both sides by 5 9X = 3,780
Divide both sides by 9 X = 420
Mahmoud has 420
