Answer 1

$1) \frac{3}{4} \times 120 = 3 \times 30 = 90$

$\frac{3}{4} \times 80 = 3 \times 20 = 60$

$\frac{3}{4} \times 240 = 3 \times 60 = 180$

$\frac{3}{4} \times 16 = 3 \times 4 = 12$

$2) \frac{3}{6} \times 48 = 3 \times 8 = 24$

$\frac{3}{6} \times 30 = 3 \times 5 = 15$

$\frac{3}{6} \times 24 = 3 \times 4 = 12$

$\frac{3}{6} \times 42 = 3 \times 7 = 21$

$3) \frac{7}{8} \times 240 = 7 \times 30 = 210$

$\frac{7}{8} \times 720 = 7 \times 90 = 630$

$\frac{7}{8} \times 480 = 7 \times 60 = 420$

$\frac{7}{8} \times 560 = 7 \times 70 = 490$

$4) \frac{6}{9} \times 270 = 6 \times 30 = 180$

$\frac{6}{9} \times 360 = 6 \times 40 = 240$

$\frac{6}{9} \times 450 = 6 \times 50 = 300$

$\frac{6}{9} \times 630 = 6 \times 70 = 420$

$5) \frac{3}{5} \times 300 = 3 \times 60 = 180$

$\frac{3}{5} \times 450 = 3 \times 90 = 270$

$\frac{3}{5} \times 250 = 3 \times 50 = 150$

$\frac{3}{5} \times 100 = 3 \times 20 = 60$
