write a word problem in which you multiply a fraction by a number greater than 1. Estimate the product then compare the product
tangare [24]
Answer:

Word problem: A recipe for making cookies use half cup of sugar for 1 cup of flour to make one pound of cookies. How many cups of sugar you need to make 3 pound of cookies.

As you can see to solve that problem you need to multiply the fraction 1/2, which is the number of cups needed to make 1 pound of cookies, times the number of pounds that you want to make.

So, for this problem you have to multiply 1/2 times 3.

My estimate is that the result is 1.5.

You can verify my estimate by multiplying:


        1        3x1       3
3 x ----- =  ------ = ------ = 1.5
        2.       1x2       2

So, I have shown that my estimate was correct.

(b) The area of a rectangular pool is 5488 m\2 If the length of the pool is 98 m, what is its width?​
mrs_skeptik [129]

Answer:

56

Step-by-step explanation:

To find the area of a rectangle we have the foruma A=WxL.

But we already have the area and length so we can plug that in

5488=Wx98

Now its an algebreic expression.

SInce its multiplying we do the opposite, so we divide 98 on both sides.

98/98 crosses itself out so now its 5488/98. Which equals 56. So now our expression is W=56. To fact check we put the numbers 56 and 98 into the formula to see if we get 5488.

A=56x98

A=5488
