Answer:
Step-by-step explanation:
Find the value of the left hand side (LHS)
LHS = 1/4 // 5/6
LHS = 1/4 * 6/5
LHS = 6/20
LHS = 3/10
Now what will make 3/10 on the right?
B: 1/4 * 6/5 = 6/20 = 3/10
a = 4
b = 6
c = 5

Scientific notation for above value is ~

Length=10
width=6
6+6+10+10=32
6×10=60
look at the factors of 60 and see what two could make 60 but also equal 32
