Tolong jawab dengan cara nya y[3 2/4+½]×10%a. 1/10b.2/5c.2 ½d.3

Jawaban :

= (3 2/4 + ½) × 10%

= (3½ + ½) × 10%

= (7/2 + ½) × 10/100

= 8/2 × 1/10

= 4 × 1/10

= (4 × 1)/10

= 4/10

= 2/5 (b)

$(3 frac{2}{4} + frac{1}{2} ) times 10% = \$

$( frac{14}{4} + frac{1}{2} ) times 10% = \$

$( frac{14}{4} + frac{2}{4} ) times 10% = \$

$( frac{16}{4} ) times 10% = \$

$frac{16}{4} times 10% = \$

$4 times 10% =$

$4 times frac{10}{100} = \$

$frac{4 times 10}{100} = \$

$frac{40}{100} = \$

$frac{2}{5} = \$

$0.4 : : atau : : frac{2}{5} : : atau : : 40% \$
