Pls Someone help me I don't understand math very well can someone help me on how to get the answer for 1/4 x 8 4/9?

Answers

Answer:

2 4/36

Step-by-step explanation:

To do this, multiply the whole number by the denominator and add it to the numerator.

8 x 9 = 72

72 + 4 = 76

76/9

Then multiply across (multiply numerators with numerators; denominators with denominators)

76 x 1 = 76

9 x 4 = 36

76/36 = 2 4/36

____________________________

A faster way to do this is to multiply the whole number by the fraction and then the fraction by the fraction.

1/4 x 8/1 = 8/4 = 2

1/4 x 4/9 = 4/36

= 2 4/36

Answer:

2 1/9

Step-by-step explanation:

Multiplying fractions: Numerator times numerator over denominator times denominator. IF you have a mixed number, convert it into improper fraction, then do numerator times numerator over denominator times denominator.

1/4 x 76/9 (I got 76/9 because the 8 means 8 9/9s, so (8 x 9)=72 plus 4 because 4/9s=76/9)

1/4 x 76/9= 76/36

=38/18

=19/9

=2 1/9

Solve for x. 12(x+11) = 24

Answers

Answer:

x = -9

Step-by-step explanation:

First, divide both sides by 12 to isolate the expression, x + 11

12(x + 11)/12 = 24/12

x + 11 = 2

Then, subtract 11 from both sides

x + 11 = 2

- 11 - 11

x = -9

12(+11)=24

So first, you are going to distribute.

12x+132=24

Now, subtract 132 from both sides of the equation.

12x+132=24
-132 -132

After you do that, you should end up with..

12x= -108

Now you can then divide both sides of the equation by the same term!

12x= -108
——- ——-
12. 12

Cancel terms that are both in the numerator and the denominator, then divide the numbers

Answer:

Step-by-step explanation:

To find the range, you need to subtract the highest number from the lowest number.

So, the answer would be 58.

88-30=58

Answer:

Range=88°−30°=58°F

Step-by-step explanation:

The Range is the difference between the highest and the lowest values.

It tells us how far apart or how how widely spread the values are.

Range=88°−30°=58°F

In this month of July, all the values are within 58 ° of each other.

No, it's not because 6 x 4 = 24 and 2 x 3 = 6.

Step-by-step explanation:

In order for it to be equivalent, the simplified ratio needs to be multiplied by the same number, meaning because 6 x 4 = 24, the next number needs to be the product of 2 x 4, not 2 x 3.

24:6 is equivalent to 6:2 because 6 times 4 is 24 and 2 times 3 is 6

Step-by-step explanation:

9 miles every week. and that for 52 weeks.

how do we calculate how many miles that are ?

well, one basic approach is

9 miles

... 52 times adding 9 miles.

in math we have a shortcut for that : we multiply. the hint is already in the "times" expression. we take 9 miles 52 times.

9 × 52 = 468 miles
