So 52 words per 1 minute

364 words per x minute
52:1 as is 364:x so
divide 364 by 52 and get 7
she typed 7 minutes

so 40% means 40/100 or 4/10

so 364=4/10
divide 364 by 2
364/2=182=2/10
multiply 182 by 5 ( to make 2/10 into 10/10) and get 910=words total to type

BUT WE WANT TO FIND WORDS LEFT so
910-364=546
she has 546 words left to type

Ling can type 52 words.
52 words=1 minute
364 words is 40%
728 words is equal to 80%
182 words is 20%. Add the 80% and the 20% to equal
910 words as the full total.
Ling has already been typing for 7 minutes, because the 364 divided by 52 is 7.
So the 910 total take away the 364 she already typed = 546 words left to type. Ling has already been typing for 7 minutes, because the 364 divided by 52 is 7.

Why are the solutions to the proportions 40/8 = x/10 and x/40 = 10/8 the same?

romanna [79]

Answer:

Both proportions are equivalent.

Step-by-step explanation:

We have been given two proportions $\frac{40}{8}=\frac{x}{10}$ and $\frac{x}{40}=\frac{10}{8}$ . We are asked to find why the solutions to our given proportions are equal.

We can solve proportions by cross multiplying them.

After cross multiplying our both proportions we will get same equation that is:

$40*10=8*x$

$400=8x$

$8*x=40*10$

$8x=400$

Since we get same equation after cross multiplying both proportions, therefore, the solutions to the given proportions would be same.
