Answer:
a. Fraction of earnings that Mariano put into each piggy bank is 1/12
b. Mariano earns $28.8
Step-by-step explanation:
Mariano divides his earning in a saving account and 3 piggy banks.
First , we have to know the fraction that we divide in the 3 piggy banks.
Piggy banks =Total earning-Saving account
Saving account 3/4,
Total earning is 1
to rest both term we have to get the same denominator , so we can say that the total earning is 4/4
Piggy banks =4/4-3/4=( 4-3)/4=1/4
Piggy banks =1/4
Each piggy bank will be 1/3 of that 1/4
1/3 x 1/4=
For fraction multiplication, multiply the numerators and then multiply the denominators to get
1×1/3×4=1/12
This fraction cannot be reduced.
b. Mariano adds $2.40
1/12 is 2.40
total earning is ?
We use cross-multiplication
a/b=c/d replacing (1/12)/2.40 = 1/ ?
So, the total earning (?) is 1 x 2.40/ (1/12)
= 2.40 x 12=$28.8
Answer:
Option B. start fraction, 2, divided by, x, end fraction, equals, start fraction, 3, divided by, dollar sign, 2, point, 91, end fraction
Step-by-step explanation:
<u><em>The correct question is</em></u>
3 folders cost $2.91 which equation would help determine the cost of 2 folders
we know that
3 folders cost $2.91
so
by proportion
Determine the cost of 2 folders
Let
x ----> the cost of 2 folders
solve for x
therefore
The cost of 2 folders is $1.94
Answer:
$4.00
Step-by-step explanation:
Multiply the 1.6 pounds of grapes by the $2.50 per pound.
X would equal 1 in this problem since 1+2=3 and the absolute value(s) in this equation would be -1+(-2)=3 since, a negative plus a negative equals a positive.
