Answer:

3/25

Step-by-step explanation:

Rewrite the decimal number as a fraction with 1 in the denominator

0.12=0.121

Multiply to remove 2 decimal places. Here, you multiply top and bottom by 10^2 = 100

0.12/1×100/100=12/100

Find the Greatest Common Factor (GCF) of 12 and 100, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 4,

12÷4/100÷4 = 3/25

Therefore

0.12 = 3/25

Svetach [21]

Answer:

Jan brought 44 cookies

Step-by-step explanation:

To solve this problem, we need to work backwards. First, we have 10 cookies left at the end of the day. At lunch, she gave away 12 cookies. This means that Ms. Jan had 22 cookies at lunch since

10 + 12 = 22

In the morning, Ms. Jan gave out half of her cookies. This means that she started with twice as many cookies as she had at the beginning of lunch.

22 x 2 = 44

Ms. Jan brought 44 cookies.

How do you solve 6x + 2(x-4)=8+4(x+2)

babunello [35]

Answer:

$\LARGE{ \underline{\underline{ \sf{\pink{ Required\: answer:}}}}}$

6x + 2 ( x - 4) = 8 + 4 ( x + 2)

6x + 2x - 8 = 8 + 4x + 8

Arranging like terms 

6x + 2x - 4x = 8 +8 - 8

8x - 4x = 8

4x = 8

x = 8/4

x = 2
