jamie and Lauren are playing a game of fraction war. They pick 2 cards each and try to make the greatest fraction. If Jamie pick

Sophie [7]

If they both aren't exchanging the cards and making the fractions from their own picked ones, then Jamie will will have 7/10 and Lauren will have 6/12.
7/10 is a bigger fraction to 6/12

6/12 is 1/2 in simplified form. To check answer- in decimal format, 7/10=0.7 and 1/2 is 0.5. So, we can say for sure that 7/10 is the greatest fraction.

When solving -1/8 (x + 35) = −7, what is the correct sequence of operations?

mariarad [96]

<u>ANSWER: </u>

Division, multiplication, addition is the correct sequence of operations for solving $-\frac{1}{8}(x+35)=-7$

<u>SOLUTION: </u>

Given, equation is $-\frac{1}{8}(x+35)=-7$

We need to solve the given equation in correct sequential order.

So, let us follow the BODMAS rule.

BODMAS means sequence of operations are brackets, orders, division, multiplication, addition, subtraction

Now,

$-\frac{1}{8}(x+35)=-7$

As the term in brackets cannot be processed further we can go for next term.

Now the division operation has to be done first according to BODMAS

- 0.125(x+35)= -7

Multiplication comes second in order.

-0.125x+4.375= -7

On rearranging the terms, we get

-0.125x+4.375+7=0

Now perform addition according to BODMAS

-0.125x+11.375=0

0.125x=11.375

$x=\frac{11.375}{0.125}=91$

Hence division, multiplication, addition is the correct sequence of operations for solving $-\frac{1}{8}(x+35)=-7$

8 and 9/10 minus 3 and 1/4 equals

maxonik [38]

Answer:

The correct answer is 17/4, from 8 and 9 from the top PLUS 3 and 1 from the bottom.

Step-by-step explanation:

If we have a mathematical problem, it's important to follow all of the steps. In this instance, we have to reduce our fractions as well as pay attention to how they are grouped together before dividing out what remains. This means that if we break it into three groups - 8 and 9 11/2 groups - 3 and 1 17/4, then divide everything by 4 with a remainder of 2/4....we get a total of 17/4 remaining which is equal to 5 1/8 = 62%.

Suppose y varies directly with x. Write a direct variation equation that relates x and y. y=7 1/2 when x=3

kolbaska11 [484]

Answer:

y/x = 2.5

Step-by-step explanation:

y ∝ x

change ∝ to = by adding constant k or c

y = kx

Divide both sides by x

y/x = k, also k = y/x

Input the values

k = (7 1/2)/3. Change 7 1/2 to improper fraction to give 15/2

k = (15/2)/3

k = $\frac{15}{2}$ ÷ 3

Change the division sign to multiplication which will change 3 to its inverse(1/3)

k = $\frac{15}{2}$ × $\frac{1}{3}$

k = $\frac{15}{6}$

Divide the numerator and denominator by 3 to get 5/2

k = 5/2

From y/x = k,input k into the eqn

y/x = 5/2

y/x = 2.5
