proportion rule; the product of the extreme terms of the proportion is equal to the product of the middle terms of the proportion; a and d are extreme; b and c are averages; a/b=c/d; => a•d=b•c; we multiply according to the rule with a cross;
Find the unknown term of the proportion:
4.8/x=1.6/7,
X•1.6=4.8•7
1.6x=33.6
X=33.6:1.6
X=21
Examination
4.8/X=1.6/7
48/10:21=16/10:7
24/5• 1/21=8/5• 1/7
24/105=8/35
8/35=8/35

We have step-by-step solutions for your answer!
