Answer: three- fourths = 21/28
Step-by-step explanation:
Hi, to answer this question we have to express the fractions in decimal form.
If both sides are equal the proportion is valid
• 3/4 = 21/28
0.75 = 0.75
• 5/6= 29/30
0.83333 ≠0.966666
• 4/7=16/49
0.57≠0.32
• 2/5=12/15
0.4 ≠0.8
So, the valid proportion is three- fourths = 21/28
