Jonas is making a trail mix recipe that calls for 3 cups of nuts and 1 cup of raisins. Jonas mixes the nuts and raisins together. He will then divide the mixture into plastic bags containing 1/2 of trail mix in each bag. How many plastic bags does Jonas needs?

You need 2 bags because you put 1/2 on each bag mix all and 1 and you put 1/2 on the first bag so you need a second bag to put the rest of the mix

Percent what is 12% of 1120 of

1120..............100%

X....................12%

X=1120·12:100

X=134,4

The answer is: 134,4.

X....................12%

X=1120·12:100

X=134,4

The answer is: 134,4.

Percent means parts out of 100

12%=12/100=1.2/10=0.12/1=0.12

12% of 1120

'of' can be tralsated as multiply

12%=0.12

0.12 times 1120=134.4

12%=12/100=1.2/10=0.12/1=0.12

12% of 1120

'of' can be tralsated as multiply

12%=0.12

0.12 times 1120=134.4

Is three fourths greater than nine tenths ?

3/4 = 0.75

9/10 = 0.90

0.90 - 0.75 = 0.15 (which is a positive difference)

this means that 0.90 is greater than 0.75

so the answer is: no, 3/4 is less than 9/10

9/10 = 0.90

0.90 - 0.75 = 0.15 (which is a positive difference)

this means that 0.90 is greater than 0.75

so the answer is: no, 3/4 is less than 9/10

no when you convert both into decimal 0.75 is smaller than 0.9.

Step-by-step explanation:

When it comes to adding and subtracting decimals. You have to line up the decimal point. You would line up to where the tenths place are lined up, like 2 and 5. Make sure the tens place is lined up too. Then you solve. Add 2 and 5=7. Then add 8 and 6= 14. Then you drop the decimal point straight down! I hope this helped!

ericka, a realestate agent, specializes in leasing apartments. her commision is 150% of her clients monthly rent. last week, she earned $850 in commision for an apartment that she helped her client to lease. how much is the monthly rent? please help show working out

The monthly rent Ericka paying is $566.67.

What is Division?A division is a process of splitting a specific amount into equal parts.

Let's x be the monthly rent that Ericka's client is paying.

We know that Ericka's commission is 150% of the monthly rent

150% of x = 1.5x

Ericka earned $850 in commission for this apartment

1.5x = 850

we need to isolate it on one side of the equation.

We can do this by dividing both sides by 1.5:

x = 850/1.5

x = 566.67

Therefore, the monthly rent is $566.67.
