Scrat [10]

Answer:

  1. 1 5/12
  2. 60 1/16
  3. 11/35

Step-by-step explanation:

1) 4 2/3 - 3 1/4 = (4 -3) +(2/3 -1/4) = 1 + (8/12 -3/12) = 1 5/12

__

2) (7 3/4)/(8/62) = (31/4)(62/8) = (31/4)(31/4) = 961/16 = 60 1/16

__

3) (2 5/7 +3 2/3) -(4 2/3 +1 2/5) = (2 + 3 -4 -1) +(5/7 +2/3 -2/3 -2/5)

  = 5/7 -2/5 = (25 -14)/35 = 11/35

_____

<em>Notes on arithmetic with fractions</em>

It can be helpful to make use of a common denominator when adding or subtracting fractions. Your knowledge of multiplication tables can help you find a suitable common denominator. Without too much effort, you can use the product of denominators as the common denominator, though doing that may require you to reduce the resulting fraction.

__

If you need a formula for addition or subtraction of fractions, this is it:

  a/b + c/d = (ad +bc)/(bd)

A sign can be attached to any of these numbers, so that ...

  a/b - c/d = (ad -bc)/(bd)

Using this formula is how we worked problem 3. It is essentially the same as rewriting each fraction to use the common denominator bd:

  a/b = ad/(bd)

  c/d = bc/(bd)

__

Of course, division of fractions (or any sort of division, actually) is the same as multiplying by the inverse (reciprocal) of the denominator. The mantra "invert and multiply" can be a useful reminder of this.

Sales increased by only 12% last month. If the sales from the previous month were $152,850, what were last months sales
Tamiku [17]

Answer:

\$171,192

Step-by-step explanation:

Remember that

100\%+12\%=112\%=112/100=1.12

we know that

The sales from the previous month were $152,850

This amount represent the 100%

so

Find out what were last months sales, multiply the sales from the previous month by the factor 1.12

\$152,850(1.12)=\$171,192
