Put the following numbers in order from smallest to largest, with the smallest value at the top of the list.

Kobotan [32]

Answer:

The right order is:

0.085
1/3
2/5
60%
3/4
78%
1.05

Step-by-step explanation:

To identify the right order of the numbers given in order from the smallest to largest, you first must convert all the numbers to the same mode (fractions, decimals or percentages), in this case, I will transform all the numbers to decimals, for this you must divide the fractions or operate the percentages, and you will obtain:

0.085 = 0.085
1/3 = 0.33333333333
60% = 0.6
2/5 = 0.4
3/4 = 0.75
1.05 = 1.05
78% = 0.78

How you can see, in this form is easier than the original form, now you can identify that 2/5 (0.4) is smaller than 60% (0.6) and 1.05 is bigger than 78% (0.78).

Jisoo drank 3/8 of a quart of chocolate milk, and his friend Andrew drank 2/7 of the same quart. How much did they drink altoget

elixir [45]

Answer:

37/56

Step-by-step explanation:

If Jisoo drank 3/8 of a quart of chocolate milk, and his friend Andrew drank 2/7 of the same quart, the amount they drank altogether will be the sum of the amount they drank individually

Total = 3/8 + 2/7

Find the LCM

Total = 3(7)+8(2)/56

Total = (21+16)/56

Total = 37/56

Hence they drank 37/56 of the quartz altogether
