Zoe says 1 2/5 is equal to 5 / 7. Is she correct? Explain.

Sagot :

Answer:

no, the numerator and denominator are switched around

Step-by-step explanation:

lets convert 1 2/5 into an improper fraction first:

5 x 1 = 5

5 + 2 = 7

numerator : 7    denominator : 5

Step-by-step explanation:

no.

1 = 1/1 = 1/1 × 5/5 = 5/5

1 2/5 = 5/5 + 2/5 = 7/5

NOT 5/7.

just think in general :

1 2/5 must be larger than 1.

but 5/7 is smaller than 1.
