Allen has a photo that is 6 in by 8 in. What will the dimensions of the photo be if he scales it down by a factor of one-half ? 3 in by 4 in 6 in by 8 in 12 in by 16 in 1.5 in by 2 in
@dtan5457
just divide both sides by 2
soo can you help me?
c?
Since the dimensions are scaled down by a factor of 1/2, that means actually multiplying each dimension by 1/2.
divide by 2, or multiply by 1/2
c?
@iambatman
\[6 \times \frac{ 1 }{ 2 }~~~\text{and}~~~8 \times \frac{ 1 }{ 2 }\] remember how on the previous question I showed you how to multiply by fractions, numerator by numerator, denominator by denominator where we can treat 6 and 8 as \[6 \implies \frac{ 6 }{ 1 }~~~\text{and}~~~8 \implies \frac{ 8 }{ 1 }\]
sooo??
c?
@geny55 Why do you think its c?
No look, if I have \[\frac{ 5 }{ 1 } \times \frac{ 4 }{ 2 } \implies \frac{ 20 }{ 2 } = 10\] Because first I multiply the numerator which is the top of the fraction and denominator is below the fraction line. Does that make sense?
