Que frações equivalentes a 3/4 tem denominador 65
LuckyWell [14K]

Dada fração: 3/4

Necessidade de converter o denominador em 65.

Vamos supor que x deve estar no numerador (topo) das frações para obter 65 no denominador (abaixo) para obter a fração equivalente de 3/4.

Vamos definir uma atribuição.

\frac{3}{4}=\frac{x}{65}

Deixe-nos resolvê-lo por x agora.

Na multiplicação cruzada, obtemos

4x = 195.

Dividindo ambos os lados por 4, obtemos

x = 48.75

Assim, podemos fazer uma fração equivalente de 3/4, colocando 48.75 no topo do denominador 65.

Então, temos \frac{48.75}{68}

Eric used to practice football for 90 minutes every day. Now, he practices 200% as many minutes as he used to. How many minutes
densk [106]
X/90 = 200/100  is/of = %/100
so cross multiply 90 and 200 and x and 100
giving you 18000 = 100x
divide both sides by 100
180=x
