1. B. 20%
2. B. 20
3. A. 9
4. D. 200
5. C. 50
Step-by-step explanation:
1. 9/45= .2×100 =20%
2 .STEP 17 = 35% × Y
STEP 27 =
35
100
× Y
Multiplying both sides by 100 and dividing both sides of the equation by 35 we will arrive at:
STEP 3Y = 7 ×
100
35
STEP 4Y = 7 × 100 ÷ 35
STEP 5Y = 20
3. 15/100 =0.15
0.15 * 60 = 9
4. 24% <> 48
1% <> 48/24
100% <> 48/24*100
=200 marbles
5. 60÷2 =30
100÷2 =50
