so I know the answer of 7/8-1/4 is 5/8 or 0.625 but i dont know how to show the working out, can someone help asap?
Simplify the following: 7/8-1/4
Put 7/8-1/4 over the common denominator 8. 7/8-1/4 = 7/8-(2)/8: 7/8-(2)/8
7/8-2/8 = (7-2)/8: (7-2)/8
7-2 = 5: Answer: | 5/8
7/8 = 0.875
1/4 = 0.25
7/8 - 1/4
= 0.875 - 0.25
= 0.625
7/8-1/4 is 5/8 or 0.625
\(\frac{7}{8}-\frac{1}{4}\\ \mbox{The denominators must be the same}\\ =\frac{7}{8}-\frac{1*2}{4*2}\\ =\frac{7}{8}-\frac{2}{8}\\ =\frac{7-2}{8}\\ =\frac{5}{8}\\ \)
