Since the question wants to know how many ingredients she used, All we have to do is add them.
So as the question says, she used 6/10 flour, 3 eggs, and 4/5 sugar.
Now we have two fractions in this scenario. Let's make them have the same denominator. Either we divide 6/10 by 2 or multiply 4/5 by 2. Let's multiply.
4/5 × 2 = 8/10
Now we have 6/10, 3, and 8/10
Lets add them together.
3 + 6/10 = 3 and 6/10
Now 3 and 6/10 + 8/10 = 4 and 4/10
Simplify even further...
and your answer will be 4 and 2/5

Answer:
<u>The number of pens = 120 and the number of pencils = 200</u>
Step-by-step explanation:
Let the number of pens x, and the number of pencils is y
the cost of one pen $1, and the cost of one pencil $0.5
The cost of the whole purchase was $220
1 * x + 0.5 * y = 220
x + 0.5 y = 220 ⇒ eq.(1)
there were 80 more pencils than pens
y - x = 80 ⇒ eq.(2)
from eq.(2) x = y - 80
By substitution with x from the last equation at eq.(1)
∴ (y - 80) + 0.5 y = 220
1.5y = 220 + 80 = 300
y = 300/1.5 = 200
x = y - 80 = 200 - 80 = 120
<u>So, the number of pens = 120 and the number of pencils = 200</u>
Answer:
W=32
L=70
Step-by-step explanation:
L=2w+6
204=2L+2W
204=2w+2(2w+6)
204=2w+4w+12
192=6w
w=32
L=2(32)+6
L=70
