1.8 c = 7.5 c = 1.8 7.5 c = 1 10 8 5 10 5 = 1 5 4 5 2 1 c = 4 9 2 11 = 2 11 ∗ 9 4 c = 9 22
C= 4.166666... or C= 7.5/1.8 You need to get C alone so you divide 1.8 from 7.5.
To solve 1.8 c = 7.5 for c , divide both sides by 1.8 to get c = 1.8 7.5 . This can be calculated to be approximately 4.17 or expressed as the fraction 6 25 .
