solve this equation
a divided into 7=20 the actual problem has the divide sign.
I got a=20*7
so a=140
Correct.
With these type of math problems, you cancel the division by multiplication. That totals: "a=20*7". If you do something on one side, you must do to the other side, so this is correct. Next, you solve by multiplying 20 and 7 together. This is "a=140". So, like what Ms. Sue said, "a=140" is correct for this problem.
To solve the given equation "a divided into 7 = 20", you are correct to multiply 20 by 7 to find the value of a. Let me explain the steps in detail:
To solve equations involving division, we need to think of it as the opposite operation of multiplication. Dividing by a number is the same as multiplying by its reciprocal.
The given equation is: a ÷ 7 = 20
To isolate the variable "a," we can multiply both sides of the equation by 7 because multiplication is the inverse operation of division:
(a ÷ 7) x 7 = 20 x 7
On the left side, the 7 and ÷7 cancel out, leaving us with just "a":
a = 140
Therefore, the solution to the equation "a ÷ 7 = 20" is a = 140.
