Question

hiroshi spends 30 minutes on history homework, 60 minutes on english homework, and x minutes on math homework. one fourth of his total homework time is spent on math. which equation can be used to find the amount of time hiroshi spends on his math homework? (x 30 60) = x (x) = x(30 60) x(30 60) = x (x) = (30 60)

Answer 1

Well, this is my type of answer.
30+60min=90min(history+english)
1/4=maths
3/4=history+english
90min/3=30min(his math homework)

Answer 2

`(1)/(4) (30+60+x)=x`

Explanation:

Here, x represents the number of minutes Hiroshi spent on math homework,

Given,

The number of minutes he spent on history = 30,

And, the number of minutes he spent on english = 60,

Thus, the total number of minutes he spent on the above three subjects = 30 + 60 + x

According to the question,

1/4th of the total time in all subject homework = Time on math homework

`\implies (1)/(4) (30+60+x)=x`

Which is the required equation.
