#2. 36

#3. 22

#4. 7.25

Step-by-step explanation:

#1: 60÷11=5.45  ----> 5.45×16=<u>87.27</u> <This is a non-terminating decimal>

#2: 60÷5= 12 ----> 12×3= <u>36</u>

<u></u>

#3: Games- 35    Won- 14    Lost- 21

      In 1 Game  Manchester won =   14/35  =  2/5 games in 54 Game  Manchester won =  54 x  2/5   games

= 108 / 5

= 21.6

<u>= 22</u>

<u></u>

#4: 6 : 91 ⇒ n : 110

     6(110) ⇒ 91(n)

     660 ⇒ 91n

     660/91 ⇒ n

     <u>7.25=n</u>

100 × (1 + 10%)

100 × (1.1)

Talking to Your Parents

Sure, you talk to your parents, but what if you need to really talk? Maybe you have a problem you can't solve alone. Or it could be that you want to feel closer to your Mom and Dad.

It's easy to say "Hi, Mom" or "Dad, can you pass the potatoes?" It can be harder to start talking about personal topics. Still, it's good to confide in your parents. In fact, it can help a lot.

Be Brave and Start Talking

Let's face it, talking about personal stuff can feel embarrassing. But remember, your parents know you pretty well — and they were your age once, too! So don't let a little embarrassment stop you. It's OK to go ahead and share what's on your mind.

Some kids might think if they share a problem, they'll make a parent worried or upset. But your mom or dad can handle knowing about your problem, big or small. If they look concerned, it just means they care, and that they feel for you.
