Question

Simplify 3 upon 4 + 1 upon 2 into 2 whole 1 upon 2 minus 2 upon 3 into 7 upon 8 divided by 5 by 4

Answer 1

Answer:

$\frac{23}{15} = 1.5$

Step-by-step explanation:

$\frac{3}{4} + \frac{1}{2} \times 2\frac{1}{2} - \frac{2}{3} \times \frac{7}{8} \div \frac{5}{4} \\ = \frac{3}{4} + \frac{1}{2} \times \frac{5}{2} - \frac{14}{24} \times \frac{4}{5} \\ = \frac{3}{4} + \frac{5}{4} - \frac{56}{120} \\ = \frac{90 + 150 - 56}{120} \\ = \frac{184}{120} \\ = \frac{23}{15} \\ = 1.5$
