Mathematics
1 answer:
valina [46]2 years ago

Answer:

4 2/7 - 6/7 = 24/

7

= 3 3/

7

Step-by-step explanation:

Conversion a mixed number 4 2/

7

to a improper fraction: 4 2/7 = 4 2/

7

= 4 · 7 + 2/

7

= 28 + 2/

7

= 30/

7

To find a new numerator:

a) Multiply the whole number 4 by the denominator 7. Whole number 4 equally 4 * 7/

7

= 28/

7

b) Add the answer from previous step 28 to the numerator 2. New numerator is 28 + 2 = 30

c) Write a previous answer (new numerator 30) over the denominator 7.

Four and two sevenths is thirty sevenths

Subtract: 30/

7

- 6/

7

= 30 - 6/

7

= 24/

7

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(7, 7) = 7. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 7 × 7 = 49. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - thirty sevenths minus six sevenths = twenty-four sevenths.

Marcus has one book less than three times the number of books that Jessie has. Use the algebra tiles to create a model of the nu
Talja [164]

Answer:

Let's define the variables:

M =  number of books that Marcus has.

x =  number of books that Jessie has.

We know that:

"Marcus has one book less than three times the number of books that Jessie has."

Then the equation that represents the number of books that Marcus has is:

M = 3*x - 1.

Then if x tiles represent the number of books that Jessie has, the number of tiles for Marcus will be 3 times that, and then subtract one tile.

Data can be analysed in a situation when one wants to know how increase in price has an effect on purchasing power.

<h3>What is a trend?</h3>

It should be noted that a trend simply means the general direction or price over a period of time. A situation when I need data was when I wanted to know how increase in prices had an effect in one's purchasing power.

To get the data, I had to take the prices of goods when there was no inflation and prices when there was inflation and how they had an impact on income.

It showed that an inverse relationship existed as an increase in prices had a negative impact on one's purchasing ability.

6. If you need to dissolve 8 tablets of active ingredient B, each containing 3 mg, in 15,750 mL, what is the ratio strength (w/v
Nuetrik [128]

Answer:

1 : 656250

Step-by-step explanation:

It is given that we need to dissolve 8 tablets of active ingredient B, each containing 3 mg, in 15,750 mL.

Tablets = 8

Weight of each tablet = 3 mg

Total wight of tablets = 8 × 3 = 24 mg

Total volume = 15,750 mL.

1 mL = 1000 mg

Total volume = 15,750000 mg

We need to find the ratio strength (w/v).

Ratio=\frac{\text{Total wight of tablets}}{\text{Total volume}}

Ratio=\frac{24}{15,750000}

Ratio=\frac{1}{656250}​

Therefore, the ratio strength (w/v) is 1 : 656250.
