Answer:
d the expression with the fractions three fifths minus one half is equal to the expression with the fractions six tenths minus five tenths is equal to the fraction one tenth
Step-by-step explanation:
Chris requires three fifths liter of paint to complete a poster. He has one half liter of paint. Which equation can be used to find the fraction of a liter of paint Chris still needs to complete the poster?
The fraction of a liter Chris requires to complete his painting is given as:
3/5 liter = 1/2 liter + x
x = 3/5 - 1/2
Lowest Common Denominator = 10
x = 6 - 5/10
x = 1/10
option d is the correct option.( the expression with the fractions three fifths minus one half is equal to the expression with the fractions six tenths minus five tenths is equal to the fraction one tenth)
Step-by-step explanation:
Let F = The number of $5 bills and T = the number of $10 bills. She has 15 bills total, so:
F+T = 15
T = 15-F
She has $120 total:
$120 = ($5)*F + ($10)*T
$120 = $5*F + ($10)*(15-F) [Substitute 15-F in place of T]
120 = 5F + 150 - 10F
-30 = -5F
6 = F
Check:
T= 15-F = 15=6 = 9
$120 = ($5)*6 + ($10)*9
$120 = $30 + $90
$120 = $120
