Question

2 1/7:(15a)=5 1/4:(0.8)

Answer 1

Answer: $a=0.021$

Step-by-step explanation:

1. To solve the expresion given in the problem above you must apply the following proccedure:

- Convert mixed numbers to decimals. Divide the numerator and the denominator of the fraction part and add the result to the whole part:

$2+\frac{1}{7}=2+0.14=2.14$

$5+\frac{1}{4}=5+0.25=5.25$

- Rewrite the expression:

$\frac{2.14}{15a}=\frac{5.25}{0.8}$

- Now, you can solve for $a$:

$0.14=6.56a\\a=\frac{0.14}{6.56}\\a=0.021$
