Write a statement as an equation: 4 times a number equals 40 . (A) 4× y=40 (B) 4+y=40 (C) 4=y ×40 (D) 4×40=y

Translate Equation: Translate the statement into an equation. The statement ＂4 times a number equals 40＂ can be written as an equation by replacing ＂a number＂ with a variable, let's use 'y', and ＂4 times＂ with multiplication. So, the equation is 4×y=40.Check Other Options: Check the other options for correctness. The second option, 4+y=40, implies addition, not multiplication, so it does not represent ＂4 times a number.＂ The third option, 4=y×40, is not correct because it implies that 4 is equal to 40 times a number, which is not what the statement says. The last option, 4×40=y, is also incorrect because it implies that the number y is equal to 4 times 40, which is 160, not 40. Therefore, the only correct equation that represents the statement is the first option, 4×y=40.

Q. Write a statement as an equation:

4

times a number equals

40

\newline

(A)

4 \times y=40

\newline

(B)

4+y=40

\newline

(C)

4=y \times 40

\newline

(D)

4 \times 40=y

Translate Equation: Translate the statement into an equation. $\newline$ The statement ＂ $4$ times a number equals $40$ ＂ can be written as an equation by replacing ＂a number＂ with a variable, let's use 'y', and ＂ $4$ times＂ with multiplication. So, the equation is $4\times y=40$ .
Check Other Options: Check the other options for correctness. $\newline$ The second option, $4+y=40$ , implies addition, not multiplication, so it does not represent ＂ $4$ times a number.＂ The third option, $4=y\times40$ , is not correct because it implies that $4$ is equal to $40$ times a number, which is not what the statement says. The last option, $4\times40=y$ , is also incorrect because it implies that the number $y$ is equal to $4$ times $40$ , which is $160$ , not $40$ . Therefore, the only correct equation that represents the statement is the first option, $4=y\times40$ $0$ .
