ANSWER:⇒ ⁶¹/₂₀
Can also be wrote out like:⇒ 3.05, 3¹/₂₀
Formulate & Calculate:
⁶¹/₄ × ₅
Calculate the product or quotient:
⁶¹/₂₀
Answer:
Step-by-step explanation:
To write fractions with a common denominator, you will most likely need to scale some numbers up! I will explain how.
Let's try it with the fractions
2
3
and
3
12
12 is larger than 3, so we will have to multiply the 3 by some number to equal 12. (We are really finding the Least Common Multiple of the two denominators!) To do this, you have to multiply the 3 by 4, because 3x4=12. But now the numerator doesn't match the denominator. When you scale the denominator up, you have to scale the numerator up too! So the 2 must be multiplied by 4 also.
Now you have the following:
8
12
and
3
12
These fractions now have common denominators! Now they're all set for adding or subtracting fractions.
Try another:
2
6
and
3
5
: The least common multiple of 6 and 5 is 30. (the product of the denominators)
Transform each fraction by multiplying by "1":
2
6
⋅
5
5
=
10
30
and
3
5
⋅
6
6
=
18
30
One last problem:
4
9
and
7
6
What is the least common multiple of 9 and 6? Could you use 54? Absolutely, but it is not the LEAST number that you could use. How about 18? YES!
4
9
⋅
2
2
=
8
18
and
7
6
⋅
3
3
=
21
18

Answer:
114%
Step-by-step explanation:
okay, so we know he spent 22 minutes on math and 25.08 on spelling.
m=22
s=25.08
so to find a percent, you have to divide s/m
s/m= 25.08/22
s/m= 1.14
because this is a decimal, we have to convert it to a percent
114%
to check the answer, multiply 22 times 114%
the answer is 25.08, so we know we got the right answer.
Answer:
J. (2, -3)
Step-by-step explanation:
1. Substitute y = x - 5 in for y in the other equation:
5x + 2(x - 5) = 4
2. Simplify:
5x + 2x - 10 = 4 (distributed the 2)
7x - 10 = 4
3. Isolate for x:
7x - 10+10 = 4+10
7x = 14
7x/7 = 14/7
x = 2
4. Plug the new x value into an equation and solve for y:
y = 2 - 5
y = -3
hope this helps!
