Answer: 7 5/7 (the bottom one)
Step-by-step explanation:
30 divided by 2 = 15 (do the same to 42 and get 21)
This then creates the fraction: 15/21
Now, divide this fraction by 3 and get 5/7
Add back in the seven because you aren't dividing the whole number.
Your final answer is now 7 and 5/7 (together: 7 5/7)
Answer:
x=-10
Step-by-step explanation:
2(x+3)=x-4
2*x+2*3=x-4
2x+6=x-4
2x-x=-4-6
x=-10
1/3 + 2/5 • 2/3
2 • 2 = 4
