Answer:
Fraction is
Step-by-step explanation:
Let x be the number of Matt's pen
and y be the number of Sarah's pen
4/5 of Sarah's pen (y) = 1/3 of Matt's pen (x)
So equation becomes
Solve for y
Multiply both sides by 5/4
Total number of Matt's and Sarah's pen = x+y
Total number of pens =
Take LCD 12
Now add the numerators
To express the number of Matts pens as a fraction
We divide the number of Matt's pen 'x' by the total number of pens
we cancel out x at the top and bottom
Take reciprocal of 17/12 and multiply with top 1
So answer is 12/ 17

3 oz = 0.75$
6 oz = 1.5$
about 7 I believe for $2
If we know the ration is 4:7, we know that both 4 an 7 need to be multiplied by the same exact number to equal 350. That leads us to set up the following equation:
4x + 7x = 350
We combine like terms to get:
11x = 350
We divide by 11 on both sides to get:
x= 31.82
7x represents the number of girl so :
7 * 31.82 = 222.72
Because the question says to round down, the answer is 222
