Question

Evaluate the following expression 7/12 −b∙ 4/15 if b= 5/16

Answer 1

Answer:

The value of the expression = 1/2 = 0.5

Step-by-step explanation:

Given

$\frac{7}{12}-b*\frac{4}{5}$  and b = $\frac{5}{16}$

Substitute with b at the given expression :

$\frac{7}{12} -\frac{5}{16} *\frac{4}{15} \\=\frac{7}{12} -\frac{5}{4*4} *\frac{4}{5*3} \\=\frac{7}{12} -\frac{1}{4*3} \\=\frac{7}{12} -\frac{1}{12} \\=\frac{7-1}{12} \\=\frac{6}{12} \\=\frac{1}{2}$
