1. 3/d = 12/20

2. 7/8 = m/48​


Sagot :

3x4 = 12 so 20/4= 5
And 8x6=48 so 7x6 = 42

Step-by-step explanation:

[tex] \frac{3}{d} = \frac{12}{20} \\d \times 12 = 3 \times 20 \\ 12d = 60 \\ d = \frac{60}{12} \\ d = 5 \\ \\ \frac{7 }{8} = \frac{m}{48} \\ 8 \times m = 7 \times 48 \\ m = \frac{7 \times 48}{8} \\ m = 42[/tex]
