Question

Paulie multiplies two numbers whose product is 1. If one of these numbers is 2, what is the other number?

Answer 1

pauli multiplies two numbers so

xy

it says the pproduct is 1 so

xy = 1

one of the numbers is 2 so let x = 2

2y = 1

what would be y?

Answer 2

it is 2

Answer 3

not exactly... 2 x 2 = 4 not 1

Answer 4

is it a one step equation

Answer 5

i believe so

Answer 6

you only do one step from

2y = 1

Answer 7

i got y=2

Answer 8

what did you do?

Answer 9

first i did it like this
2y=1
*2=*2
then i eliminated the both of the two's on the left side and then i brought down the y and did 1*2 on the right side and got y=2 that is the way my teacher taught me

Answer 10

you dont multiply by 2...if you multiply both sides by 2 you'll get

4y = 2

Answer 11

so then what do u do?

Answer 12

you \(\textbf{*divide*}\). remember \[\frac{2}{2} = 1 \; ; \; \frac{3}{3} = 1\; ; \; \frac 44 = 1\; ; \; \text{etc.}\]

Answer 13

i just worked it out and i got 2
