A. 3 1/2 + 3/4 - 5/8 = b. 2 1/4 : 1 1/4 x 1 1/4 = mohon di jawab :)

A. 3 1/2 + 3/4 – 5/8 = b. 2 1/4 : 1 1/4 x 1 1/4 = mohon di jawab :)

$sf a). : 3 frac{1}{2} + frac{3}{4} - frac{5}{8}$

$sf = frac{(3 times 2 + 1)}{2} + frac{3}{4} - frac{5}{8}$

$sf = frac{7 times4}{2 times 4} + frac{3 times 2}{4 times 2} - frac{5 times 1}{8 times 1}$

$sf = frac{28}{8} + frac{6}{8} - frac{5}{8}$

$sf = frac{28 : + : 6 : - : 5}{8}$

$sf = frac{34 : - : 5}{8}$

$sf = frac{29}{8}$

$bf = 3 frac{5}{8}$

$sf b). : 2 frac{1}{4} div 1 frac{1}{4} times 1 frac{1}{4}$

$sf = frac{(4 times 2 + 1)}{4} div frac{(4 times 1 + 1)}{4} times frac{(4 times 1 + 1)}{4}$

$sf = frac{9}{4} div frac{5}{4} times frac{5}{4}$

$sf = frac{9}{4} times frac{cancel4}{cancel5} times frac{cancel5}{ cancel4}$

$sf = frac{9}{4} times frac{1}{1} times frac{1}{1}$

$sf = frac{9}{4}$

$bf = 2 frac{1}{4}$
