1 answer:

5 0

If you dont follow the right steps in the right order or properly, you won't end up with the right answer:
For example 3 x 5 + 7
If you do multiplication then add you get 22 which is correct.... but!!
If you add then do multiplication you get 36 which isn't right

Remember always follow PEMDAS
P-Parenthesis
E-Exponents
M or D- Multiplication or division (go left to right)
A or S- Addition or Subtraction (go left to right)

Find equivalent fractions with a common denominator and order from least to greatest 2/3,1/2,5/12

ycow [4]

The common denominator is 12. 2/3 x 4/4 = 8/12, 1/2 x 6/6 = 6/12, and 5/12 already goes into the denominator 12, so you would not need to change anything.

Since 5/12 is the lowest of the group it's the last, 8/12 is the biggest, so it's first and 6/12 is in the middle.

Your answer from least to greatest is 5/12, 6/12, and 8/12

Samantha wants to use her savings of 1150 to buy shirts and watches for her family. The total price of the shirt she bought was

ioda

Answer-

The maximum number of watches that Samantha come by with her savings is 10.

Solution-

The amount of money Samantha has in her savings account = $1150

She wants to buy shirts and watches.

Cost of one shirt = $84

Cost of each watch = $99

Let she can buy maximum of x watches, so the net price of the watches is $99x.

Then,

$\Rightarrow 99x+84=1150\\\\\Rightarrow 99x=1150-84\\\\\Rightarrow 99x=1066\\\\\Rightarrow x=\dfrac{1066}{99}\\\\\Rightarrow x=10.77$

As the number of watches can not be in fraction, so at most she can buy 10 watches.
