Let the number be x
So,
$\frac{3}{4} \times 28 = \frac{30}{7} \times x \\ x = \frac{3 \times 28 \times 7}{4 \times 30} \\ x = 4.9$

Answer 2

Hey !!


Let the Number be X .



So,.

3/4 × 28 = 30/7 × x




3 × 7 = 30X/7




30X = 21 × 7


X = 21×7/30 = 7×7 / 10



X = 4.9



Hence,


3/4 of 28 is equal to 30/7 of 4.9.
