How much will two and a half pounds cost?
please put explanation thank you
3 1/2 is to $1.68 as 2 1/2 is to $_____?
Write 3 1/2 as 3.5 and 2 1/2 as 2.5
3.5 is to $1.68 as 2.5 is to $_____?
Replace the words "is to" by " / "
Replace the word "as" by " = "
Replace the $____ by x
3.5/1.68 = 2.5/x
Cross multiply.
That is, multiply the 3.5 times the x,
getting 3x, and put that on the left
side of an equal sign
3.5x =
Now multiply the 1.68 by the 2.5,
getting 4.2 and put that on the right
side of the equal sign
3.5x = 4.2
Now divide both sides by 3.5
x = 4.2/3.5
x = 1.2 or $1.20
