Plssss help<br><br>use multiplication to solve the proportion​
kobusy [5.1K]

Answer:

Its 7.333333333333333333  (3 forever)

First you isolate y onto one side of the equation

y/9= 44/54  -->  y = 9 x 44/54

Multiply the right side of the equation

9 x 44/54 = 396/54

Now divide to get the whole answer

396/54 = 7.3333333333 (3 forever)

y = 7.333333

How to explain math problems to 3rd grader
hjlf

Answer:


Step-by-step explanation:

This is a super question and it is an excellent exercise for you. When I was teaching, once every term, I would ask my physics class to explain acceleration to a 7 year old. The stats favored the older women (mothers) who took the class. Almost none of the guys could do it. Here's why.

  • The sentences had to be very short. They were barely 6 or 7 words long. They were complete sentences.
  • The examples used had to be very simple. The secret to those mother's answers was they invariably picked something like a stop sign. They all knew that and they always got it right for those reasons.

You are trying to teach a seven or eight year old. Believe it or not, the first thing you have to do is check and see if they know their facts. Can they do 7+8 or 9+ 6 without hesitancy. If they can do those facts do they know the multiplication facts. 4 * 5 etc. They must know those things cold, or you are wasting your time. Don't ask me why. But you can't go on without those 2 fact types solid.

I take it you are trying to do word problems. The best thing you can do is teach them to read.

A man has a dime and a nickel and a penny. How much money does he have? Us a marker to underline the key statement.

a dime,

a nickel

a penny should be underlined. Don't ask for an answer - yet.

======

Keep doing this problem over and over. You are not trying to get an answer. You are trying to get them to understand how to read a question

A person has just less than 4 quarters just less than 5 dimes and just less than 4 nickels. How many coins does he have. That's an important question because the grade three-er is going to have to know what less means.

That should get you started.
