Q:

when divided by 3, i am 700. when divided by 7, i am 300. what number am i?

Accepted Solution

A:
⓵ Write down both equations :

X ÷ 3 = 700

X ÷ 7 = 300

⓶ Solve both of these equations :

X ÷ 3 = 700
× 3 × 3

↓

X = 2100


X ÷ 7 = 300
× 7 × 7

↓

X = 2100


Now that you’ve solved each equation and that “X” is worth the same thing in both, you know that you calculated everything correctly!

If you really want to triple check your answers, you could test that number to see if it works :

2100 ÷ 3 = 700? → YES

2100 ÷ 7 = 300? → YES


↠ So the answer to your question is : The number is 2100.

I really hope this helped, if there’s anything just let me know! ☻
