3/4z = 2/3a
z + a = 510...z = 510 - a
3/4(510 - a) = 2/3a
382.50 - 3/4a = 2/3a
382.50 = 2/3a + 3/4a
382.50 = 8/12a + 9/12a
382.50 = 17/12a
382.50 * 12/17 = a
270 = a
z + a = 510
z + 270 = 510
z = 510 - 270
z = 240
check..
3/4z = 2/3a
3/4(240) = 2/3(270)
180 = 180 (correct)
Zul had $ 240
Zul gave 30% of his money to his sister
0.30(240) = 72
his sister received $ 72
