2 1/2 * 3
5/2 * 3/1
= 15/2
15/2 - 11 3/8
15/2 - 91/8
91/8 - 60/8
= 31/8 = 7 7/8
answer=7 7/8

Answer:
Step-by-step explanation:
Which of the following was a demand of the marchers
Thirty eight billion , four hundred million, sixty (is your answer)
4a + 9b + 0c = 8 ⇒ 4a + 9b + 0c = 8
8a + 0b + 6c = -1 ⇒<u> 8a + 0b + 6c = -1</u>
0a + 6b + 6c = -1 12a + 9b + 6c = 7
12a + 9b + 6c = 7 ⇒ 24a + 18b + 12c = 14
4a + 9b + 0c = 8 8a + 6b + 12c = 0 ⇒ <u>24a + 18b + 36c = 0</u>
8a + 0b + 6c = -1 ⇒ 8a + 0b + 6c = -1 <u>-24c</u> = <u>14</u>
0a + 6b + 6c = -1 ⇒ <u>0a + 6b + 6c = -1</u> -24 -24
8a + 6b + 12c = 0 c = ⁷/₁₂
6b + 6(⁷/₁₂) = -1
6b + 3¹/₂ = -1
<u> - 3¹/₂ - 3¹/₂</u><u>
</u> <u>6b</u> = <u>-4¹/₂
</u> 6 6<u>
</u> b = ³/₄
4a + 9(³/₄) = 8
4a + 6³/₄ = 8
<u> - 6³/₄ - 6³/₄
</u> <u>4a</u> = <u>1¹/₄</u>
4 4
a = ⁵/₁₆
(a, b, c) = (⁵/₁₆, ³/₄, ⁷/₁₂)
