Mathematics
1 answer:
Margaret [11]3 years ago
6 0

If you want to multiply a decimal by a whole number, just ignore the decimal point and multiply like normal! Then, bring the decimal point back for the answer. for example 2×0.2

first multiply 2*2=4

and then place the decimal we have one value after decimal so the answer is 0.4

Step-by-step explanation:

4\frac{9}{20} - 1\frac{2}{6} =\\\frac{89}{20}  - \frac{8}{6} = \frac{89 - 26.7}{20} = \frac{62.3}{20} \\

4\frac{6}{9}  - 3\frac{3}{6} =\\\frac{42}{9} - \frac{21}{6} = \frac{252 - 189}{54} = \frac{63}{54} = 1\frac{9}{54}

2\frac{2}{4} - 1\frac{1}{3} =\\\frac{10}{4} - \frac{4}{3} = \frac{30 - 16}{12} = \frac{14}{12} = 1\frac{2}{12}

A company has budgeted 5 1/4 hours to complete a project, with 1/3 of the time spent on research. How much time does the company
elena-s [515]

Given that a company budgeted 5 1/4 hours to complete a project, determine how much time they spent on research if they spent 1/3 of the total budget.

First, convert the budget from hours into minutes.

5 1/4 hours = 315 minutes

1 hour = 60 min

1/4 hour = 15 min

60 x 5 = 300

300 + 15 = 315

Then, divide the minutes by 3 or multiply it by 1/3.

315 / 3 = 105

315 x 1/3 = 105

Lastly convert to a mixed number.

1 3/4 hour

Thus, the company plans to spend 1 3/4 hours or 1 hour and 45 minutes on research.

What is -2+6X= -8. x=<br>​
Strike441 [17]

Answer:

x=-1

Step-by-step explanation:

So we have the equation:

-2+6x=-8

Add 2 to both sides. The left cancels:

6x=-6

Divide both sides by 6. The left cancels:

x=-1

So, the value of x is -1.

And we're done!
