So start with subtracting 12 and 8 to get 4. You know it takes 2 hours to sketch 8 of the 12 which leaves the 4 left. There are half the strips so, it will take half the time. In the end, it will take them 3 hours.
Answer:
Step-by-step explanation:
Please type numerals and punctuation for your mixed numbers.
I will have to assume that you meant 2 5/6 and 1 1/3, and that you are subtracting 2 5/6 from - 1 1/3. If that is correct, then we determine the LCD and rewrite -1 1/3 using this LCD:
-1 1/3 -1 2/6
-2 5/6 -2 5/6
----------
-3 7/6 or -4 1/6
The best calculation of this difference is -4 1/6 and the best estimate is
-1 - 3, or -4
![Fraction = \frac{36}{48}](https://tex.z-dn.net/?f=Fraction%20%3D%20%5Cfrac%7B36%7D%7B48%7D)
![Decimal = 0.75](https://tex.z-dn.net/?f=Decimal%20%3D%200.75)
![Percent = 75 \%](https://tex.z-dn.net/?f=Percent%20%3D%2075%20%5C%25)
<em><u>Solution:</u></em>
Given that,
36 rainy days out of 48 days
<h3><u>Find the fraction:</u></h3>
numerator = 36
denominator = 48
Therefore,
![Fraction = \frac{36}{48}](https://tex.z-dn.net/?f=Fraction%20%3D%20%5Cfrac%7B36%7D%7B48%7D)
<h3><u>Decimal:</u></h3>
Convert the fraction to decimal:
![Decimal = \frac{36}{48} = 0.75](https://tex.z-dn.net/?f=Decimal%20%3D%20%5Cfrac%7B36%7D%7B48%7D%20%3D%200.75)
<h3><u>Percent:</u></h3>
We have to find the percent pf 36 rainy days out of 48 days
![Percent = \frac{36}{48} \times 100\\\\Percent = 0.75 \times 100\\\\Percent = 75 \%](https://tex.z-dn.net/?f=Percent%20%3D%20%5Cfrac%7B36%7D%7B48%7D%20%5Ctimes%20100%5C%5C%5C%5CPercent%20%3D%200.75%20%5Ctimes%20100%5C%5C%5C%5CPercent%20%3D%2075%20%5C%25)
Thus percent is 75 %
Answer: 4 of $5 bags and 2 of $4 bags
4x$5=$20
2x$4=$8
$20+$8=$28
Answer:
The order in which operations should be done is abbreviated as PEMDAS
Step-by-step explanation:
The order in which operations should be done is abbreviated as PEMDAS:
Parentheses denoted by '( )'
Exponents denoted as the power of a number '^'
Multiplication denoted as product of numbers '×'
Division denoted as dividing two numbers '÷'
Addition denoted as sum of two numbers '+'
and Subtraction denoted as difference of two numbers '-'
For example,
To solve
using operation order we first solve parentheses ,
![\Rightarrow 5+(2)^2\times 3 \div 6-1](https://tex.z-dn.net/?f=%5CRightarrow%205%2B%282%29%5E2%5Ctimes%203%20%5Cdiv%206-1%20)
Then exponents,
![\Rightarrow 5+ 4\times 3 \div 6-1](https://tex.z-dn.net/?f=%5CRightarrow%205%2B%204%5Ctimes%203%20%5Cdiv%206-1%20)
then, multiplication,
![\Rightarrow 5+ 12\div 6-1](https://tex.z-dn.net/?f=%5CRightarrow%205%2B%2012%5Cdiv%206-1%20)
now, division
![\Rightarrow 5+2-1](https://tex.z-dn.net/?f=%5CRightarrow%205%2B2-1%20)
now addition and then subtraction,
![\Rightarrow 7-1=6](https://tex.z-dn.net/?f=%5CRightarrow%207-1%3D6%20)
Thus, solving
using operation order we find the value as 6.
