What is multiplication?

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

here, we have,

Given

A bread recipe requires 3/4 cup of flour

and 1/5 cup of sugar

i.e. ratio of flour and sugar is 3/4 / 1/5

which will remain same for each time we make bread

When 1 cup of flour is used then amount of sugar is

Suppose x cup of sugar is required so equating the ratio of flour to sugar

to get one cup we can multiply by the reciprocal. (the oppisite of the current fraction) 3/4*4/3 = 1.

so then we need to raise the sugar by the same variable

1/5 * 4/3. cross multiplication gives us

1*4=4

3*5=15

x = 4/15

Hence, The solution is, 4/15 is the amount of sugar that should be used with 1 cup of flour.

Where was 5/6 of a pie. Joe ate 1/6 of the pie. How much of the whole pie was left?

Answers

5/6 minus 1/6 is equal to 4/6. Good luck :)

4/6 of the pie was left:)
since the denominators are the same
the bottom numbers or in this case the number 6 in the fraction:)
all you have to do is subtract 5-1 = 4!!
so keep your denominator the same and add the new numerator
4

First question:-

Order from least to smallest.

9,3, 9 1/3, 37/4, 9.34

Now, let us get all the numbers in the same format.

37/4 = 9 1/4

9 1/4 = 9.25

9.34

9.3 = 9.30

9 1/3 = 9.33

Now order them.

Final answer: 37/4, 9.3, 9 1/3, 9.34 DONE!

Second question:-

6 1/2 + 5 1/5 = 6 5/10 + 5 2/10 = 11 7/10

11 7/10 + 2 4/5 = 11 7/10 + 2 8/10 = 13 15/10 = 14 1/2

14.5 = n + 10

Now solve for n

14.5 - 10 = n + 10
-10

4.5 = n

Final answer: n = 4 1/2

Third question:-

Reciprocity of 1 1/2

first, we make the mixed number an improper fraction.

1 1/2 = 1*2 = 2 + 1 = 3

3/2 the reciprocal of it is 2/3

Final answer: 2/3

Fourth question:-

solve the proportion.

2 2/5 minutes to run 1.5 miles.

2.4/1.5 = 1/x

Cross multiply. 2.4*x = 1.5*1

2.4x = 1.5
-------------
2.4

x = 2.4/1.5

Final answer: x= 1 3/5

Fifth question:-

x/10 = 2 2/10 <--------- i made sure the denom's are the same!

22/10 = x/10

x = 22

Final answer: x = 22

YES...WE HAVE OUR ANSWERS...AND THIS TOOK ME FOREVER. :D
