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?
Answer
A
1 fourth times x is equal to open paren 30 plus 60 close paren
B
1 fourth x open paren 30 plus 60 close paren is equal to x
C
1 fourth times open paren x plus 30 plus 60 close paren is equal to x
D
1 fourth times x is equal to x times open paren 30 plus 60 close paren
Explanation
Hiroshi’s total homework time is x + 30 + 60 minutes. Since math homework is one fourth of the total time, one fourth of that sum must equal the math time, x: 1/4(x + 30 + 60) = x. This is choice B, “one fourth times (x plus 30 plus 60) is equal to x.”
