39¹/₅ or 39.2

<h3>Further explanation</h3>

<u>The Problem:</u>

  • 7 copies of the sum of 8 fifths and 4.
  • Write an expression to match, and then evaluate.

<u>The Process:</u>

Here are some early expressions that need attention.

  • 8 fifths is \boxed{\frac{8}{5}}
  • the sum of 8 fifths and 4 is \boxed{\frac{8}{5} + 4}

7 copies of the sum of 8 fifths and 4 mean that we have to multiply 7 with the sum of 8 fifths and 4.  The term of "the product" is synonymous with multiplication.

Let us write an expression to match for '7 copies of the sum of 8 fifths and 4'.

\boxed{\boxed{ \ 7 \times \bigg(\frac{8}{5} + 4 \bigg) \ }}

Let us calculate the operation in parentheses at first.

\boxed{ \ \frac{8}{5} + 4 \ }

\boxed{ \ \frac{8}{5} + \frac{20}{5} \ }

\boxed{ \ \frac{28}{5} \ }

And now we solve the full expression.

\boxed{ \ = 7 \times \bigg(\frac{8}{5} + 4 \bigg) \ }

\boxed{ \ = 7 \times \frac{28}{5} \ }

\boxed{\boxed{ \ \frac{196}{5} \ }}

In mixed fraction:

\boxed{ \ \frac{196}{5} = \ ? \ }

\boxed{ \ = \frac{195}{5} + \frac{1}{5} \ }

\boxed{ \ = 39 + \frac{1}{5} \ }

\boxed{\boxed{ \ 39\frac{1}{5} \ }}

In decimal:

\boxed{ \ 39\frac{1}{5} = \ ? \ }

\boxed{ \ = 39\frac{1 \times 2}{5 \times 2} \ }  

\boxed{ \ = 39\frac{2}{10} \ }  

\boxed{\boxed{ \ 39.2 \ }}

Thus, the result is \boxed{\boxed{ \ 39\frac{1}{5} \ or \ 39.2 \ }}.

vic and ben's ages are in the ratio of 3:4. if vic is 12 years old and 3 months old how old is ben in years and months??
posledela
Converting their ages to months:
12*12=144months + 3 months
=147 months
Now, 3 is equivalent to 147 months;
4 will be equivalent to;
4*147/3
= 196 months
= 16 years and 4 months

how many gallons of a 50 antifreeze solution must be mixed with 90 gallons of 20% antifreeze to get a mixture that is 40% antifr
Tamiku [17]
Try this:
1) note that weight of pure antifreeze before mixing and after mixing is the same. So, if 'x' is weight of pure antifreeze in 50% solution, it is possible to make up equation before mixing: 0.5x+0.2*90.
2) there are 0.2*90=18 gal. of pure antifreeze in the 20% solution. If 'x' gal. is the weight of pure antifreeze in 50% sol. and 18 gal. is the weight of pure antifreeze in 20% sol., it is possible to make up an equation after mixing: 0.4(x+18).
3) using the both parts: 0.5x+0.2*90=0.4(x+18) ⇒ x=54 gal. of <u>pure</u> weight.
4) to find 50% solution of 54 gal. pure weight just 54:0.5=108 gal.
Answer: 108 gal.
