Answer:
1
Step-by-step explanation:
These numbers have no common factors. The only comon factor they have is one. Therefore, the GCF of 117, 19, and 110 is one.
When dividing fractions, we follow a rule called "Keep, change, flip"
Basically, you keep the first fraction the same, change the sign to a multiplication sign, and flip the second fraction.
2 = 2/1
7 * 1 + 6 = 13
2/1 * 7/13 = 14/13 = 1 1/13
2 divided by 1 6/7 = 1 1/13
3 3/5 = 18/5
2 1/4 = 9/4
18/5 * 4/9 = 72/45 = 8/5 = 1 3/5
3 3/5 divided by 2 1/4 = 1 3/5
4 1/2 = 9/2
2 3/8 = 19/8
9/2 * 8/19 = 72/38 = 36/19 = 1 17/19
4 1/2 divided by 2 3/8 = 1 17/19
Justin can make 25 scraves with 15 balls of yarn
<h3><u>Solution:</u></h3>
Given that Justin can make one scarve for 3/5 of a ball of yarn
He purchases 15 balls of yarn
<em><u>To find: number of scarves Justin can make</u></em>
Number of scarves Justin can make with 15 balls of yarn can be found out by dividing 15 balls of yarn by 3/5 of a ball of yarn
Thus he can make 25 scraves
He made his first mistake in step 5. He used the statement he was trying to prove as a reason.
hope that helps
Ok so u have to set them equal to 180 bc they r supp lines so 1.15+x=180 sub 15 from both sides x=165
2.28+x-4=180 combine like terms 28-4=24 rewrite 24+x=180 den sub 24 from both sides x=156
I will put the rest in the comments if you still don't know
