One whole jar= 3/3 or 1
Set up a ratio comparing the two sets of measurements.
2 2/4 ounces of peanuts is to 2/3 of a jar as x ounces of peanuts is to 3/3 of a jar.
x= ounces in 1 whole jar
2 2/4 / 2/3= x / 3/3
cross multiply
(2 2/4 * 3/3)= (2/3 * x)
convert to improper fractions
10/4 * 3/3= 2/3x
multiply numerators; multiply denominators
(10*3)/(4*3)= 2/3x
30/12= 2/3x
divide both sides by 2/3
30/12 ÷ 2/3= x
to divide fractions, multiply by the reciprocal/inverse of 2/3
30/12 * 3/2= x
multiply numerators; multiply denominators
(30*3)/(12*2)= x
90/24= x
simplify by 6
15/4 or 3 3/4 ounces= x
ANSWER: 3 3/4 ounces can make a full jar.
Hope this helps! :)
Answer:
Addition.
Step-by-step explanation:
Multiplication is a faster way to do repeated addition.
For example, lets say you would add 10 fifteen's together. Addition would make it:
15 + 15 + 15 + 15 + 15 + 15 + 15 + 15 + 15 + 15
= 30 + 30 + 30 + 30 + 30
= 60 + 60 + 30
= 120 + 30
= 150
However, when multiplying:
15 x 10 = 150
As you can tell, multiplication makes it so there are less steps, and is less time consuming.
~
"of" means to multiply.
20% * 60
= 0.2 * 60 (since % means divide by 100)
= 12
Student A is wrong and Student B is correct.
How?
- Direction is saying to construct a line that passes through C
- The last step is enough to describe that A is wrong.
- Its saying to swing an arc(Should be line).
- On the other hand Student B has done correct
- By passing point through C and G it satisfies our required construction.
6, 12, 18, 24.
8, 16, 24.
24 is your answer. Hoped I helped!
