I hope this helps:)
A ratio shows us the number of times a number contains another number. The ratio of DE to EF is 3:2. The ratio of DE to EF is 3:1.
A ratio shows us the number of times a number contains another number.
1.)
DE = √(6² + 3²)
= √45
= 3√5
EF = √(4² + 2²)
= √20
= 2√5
Ratio = 3√5 / 2√5 = 3/2
Hence, the ratio of DE to EF is 3:2.
2.)
PQ = √(6² + 3²)
= √45
= 3√5
QR = √(1² + 2²)
= √5
Ratio = 3√5/√5 = 3:1
Hence, the ratio of DE to EF is 3:1.
