Explain how you can determine if 1/3 and 4/12 are equivalent fractions.

Answers

The expression $(1)/(3)$ is $\boxed{{\mathbf{equivalent}}}$ to the expression $(4)/(12)$ .

Further explanation:

The number ab is the product of $a\;\text{and}\;b$ and it is the multiple of $a$ where $b$ are the integers.

It can be written as,

$ab=a* b$

Given:

The given expressions are $(1)/(3)$ and $(4)/(12)$ .

Step by step explanation:

Step 1:

The given expression is $(4)/(12)$ .

The denominator and the numerator of the given expression is the multiple of $4$ .

The denominator of the expression can be written in the multiple of 4 as,

$12=4*3$

Therefore, the number 12 is the multiple of $3\;\text{and}\;4$ .

The numerator of the expression can be written in the multiple of 4 as,

$4=4*1$

Therefore, the number 4 is the multiple of $1\;\text{and}\;4$ .

Step 2:

Now, divide the given expression $(4)/(12)$ by 4 to convert in the lowest form as,

$\begin{aligned}(4)/(12)&=(4/4)/(12/4)\n&=(1)/(3)\end{aligned}$

It can be seen that the resultant answer is $(1)/(3)$ .

Now, divide the given expression $(1)/(3)$ by 1 as,

$\begin{aligned}(1)/(3)&=(1/1)/(3/1)\n&=(1)/(3)\end{aligned}$

It can be seen that the resultant answer is $(1)/(3)$ .

Thus, it can be seen that the expression $(1)/(3)$ is equivalent to the expression $(4)/(12)$ .

Last Saturday, Jay spent 6 hours playing games, studying and talking with his friends. he spent 2/5 of the time playing games and 1/2 of the time studying. How many minutes did he spend talking with his friends?

Answers

(1 - (2/5 + 1/2)) x (6 x 60)
(1 - (4/10 + 5/10)) x 360
(10/10 - 9/10) x 360
1/10 x 360 = 36
so he spend 36 minutes talking with his friend

Final answer:

Jay spent 36 minutes talking with his friends on Saturday after spending 2/5 of his time playing games and 1/2 of his time studying.

Explanation:

The total time Jay spent on all activities is 6 hours. He spent 2/5 of his time gaming, so that would be 0.4 * 6 hours = 2.4 hours, and he spent half of his time studying, that's 0.5 * 6 hours = 3 hours. To figure out how much time he spent talking with friends, we subtract the time spent gaming and studying from the total time. So, 6 hours – 2.4 hours – 3 hours = 0.6 hour. As there are 60 minutes in an hour, Jay spent 0.6 * 60 = 36 minutes talking with his friends.

#SPJ2

four students spent $12 on school lunch .at this rate,find the amount 10 students would spend on the same school lunch

Answers

In order to solve this, we need to figure out how much ONE student spends.
$(12dollars)/(4students) = 3$ dollars per student.

If 10 student spent for lunch, we just have to multiply our number by how much each student spends.
$10students* (3dollars)/(student) = 30dollars$

ok so you will multiply 12 times 10 or you could add 12 + 12+12+12+12+12+12+12+12+12 add them up and it will be $120
