Or you could easily divide the denominator (4) into 19 and get your answer. since 4 doesnt go into 19 evenly there is going to be a decimal. so see how mang places the decimal goes out to. EX: tenths, hundredths, thousandths ect. after you have calculated that answer. put the number over tne value. for EX: 3 hundreths would be 3 over a 100. ect. nect calculate how many wholes there are and you good. Last EX: 2 wholes and 3 over 100..really simple, but I may have made it sound a tad confusing. but its really simple.

19/4 can also be written as 16/4+3/4 so the mixed fraction will be 4+3/4...in other words 4 3/4. And to check it, you can multiply the denominator (here, 4) by the whole number(here, 4) and then add the numerator(here, 3)
Which adds up to 19/4! :)

In this exercise, you're required to share the total amount of money in the ratio of 3:7. Thus, we would solve as follows:

<u>For a </u><u>ratio</u><u> of </u><u>3</u><u>:</u>

Amount=\frac{3}{10} \times 900\\\\Amount=\frac{2700}{10}

Amount = £270.

<u>For a </u><u>ratio</u><u> of </u><u>7</u><u>:</u>

Amount=\frac{7}{10} \times 900\\\\Amount=\frac{6300}{10}

Amount = £630.

A chemist is conducting an experiment which involves a certain chemical reaction. He begins the experiment with 666 milliliters
Ket [755]

Answer:

8 Minutes

Step-by-step explanation:

since we are trying to find how many minutes have passed we first need to find how much substance was used during the time. we can do that by subtracting the leftover substance from the amount we started with.

666-562 = 104

Now that we know how much substance was used we can then use our conversion rate (13 per minute) and find how many minutes have passed by dividing.

104 / 13 = 8
