Answer:
1
Combine multiplied terms into a single fraction
6−8=12(4+5)
6−8=1(4+5)2
2
Multiply by 1
6−8=1(4+5)2
6−8=4+52
3
Add
8
888
to both sides of the equation
6−8=4+52
6−8+8=4+52+8

Step-by-step explanation:
Answer:
Arnold
Step-by-step explanation:
In order to compare, you'd have to find out how much they paid for each pound of tri-tip. So, to do this, you would divide the total amount of money the spent on the pounds by the number of pounds they bought. So for Kevin, you'd divide 29.97 by 3 to get that Kevin paid $9.99 for each pound. For Arnold, you'd divide 35.96 by 4 to get that Arnold paid $8.99 for each pound. And 8.99 is less than 9.99, so Arnold was right.
Conversion a mixed number 3 3
7
to a improper fraction: 3 3/7 = 3 3
7
= 3 · 7 + 3
7
= 21 + 3
7
= 24

To find new numerator:
a) Multiply the whole number 3 by the denominator 7. Whole number 3 equally 3 * 7
7
= 21
7
b) Add the answer from previous step 21 to the numerator 3. New numerator is 21 + 3 = 24
c) Write previous answer (new numerator 24) over the denominator 7.
Three and three sevenths is twenty-four sevenths
Conversion a mixed number 4 5
7
to a improper fraction: 4 5/7 = 4 5
7
= 4 · 7 + 5
7
= 28 + 5
7
= 33

To find new numerator:
a) Multiply the whole number 4 by the denominator 7. Whole number 4 equally 4 * 7
7
= 28
7
b) Add the answer from previous step 28 to the numerator 5. New numerator is 28 + 5 = 33
c) Write previous answer (new numerator 33) over the denominator 7.
Four and five sevenths is thirty-three sevenths
Add: 24

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(7, 7) = 7. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 7 × 7 = 49. In the next intermediate step the fraction result cannot be further simplified by cancelling.
In words - twenty-four sevenths plus thirty-three sevenths = fifty-seven sevenths.
Answer:
A
Step-by-step explanation:
Answer:
150kg
Step-by-step explanation:
50 oranges ----- 7.5 kg
1000 ------- x
50 * x = 1000 * 7.5
x = 7500 / 50
= 750/5
=150
