Question 1 of 3

Assinala as frações equivalentes a \(\frac{5}{6}\).

Select one or more of the following:

\(\frac{15}{21}\)
\(\frac{30}{36}\)
\(\frac{10}{12}\)
\(\frac{2}{3}\)

Explanation

Question 2 of 3

Considera a equivalência entre as frações \(\frac{2}{3}\) = \(\frac{a}{6}\) = \(\frac{8}{b}\) = \(\frac{10}{c}\) = \(\frac{20}{d}\). Assinala a alternativa correta.

Select one of the following:

a = 4, b = 15, c = 12, d = 20
a = 4, b = 12, c = 15, d = 30
a = 2, b = 15, c = 16, d = 30
a = 4, b = 8, c = 15, d = 30

Explanation

Question 3 of 3
