Answer:

1/8

Step-by-step explanation:

ok so before i start i wanna say that this is gonna get confusing.....

Since the pizza is a whole quantity let us take it as 1.

Harry ate half of the pizza therefore the fraction that Harry ate = 1/2 of 1

= 1/2 × 1 = 1/2

Therefore fraction Harry ate = 1/2

Fraction of pizza left = 1 - 1/2 (LCM = 2)

= 1/2

Jacqueline ate 1/2 of what was left.

So, Fraction of pizza Jacqueline ate = 1/2 × 1/2 = 1/4

Therefore fraction of pizza left after both Harry and Jacqueline ate =

1 - (1/2 +1/4) = 1 - 3/4 (LCM = 4) = 1/4

Therfore fraction of pizza left = 1/4

Stanley ate 1/2 of what was left.

So, fraction of pizza Stanley ate = 1/2 × 1/4 = 1/8

Therefore, fraction of pizza left after all three of them ate =

1 - (1/2 + 1/4 + 1/8) = 1 - 7/8 (LCM = 8) = 1/8

I hope this helps .......i know this is rlly confusing but i dont know how else to put it : )

Have a nice day!

At the first track meet, Lonnie threw the shot put 51 1/3 feet. At the second track meet he threw the shot put 54 1/2 feet. Writ

mars1129 [50]

Answer:

Step-by-step explanation:

At the first track meet, distance of the shot put throw $D_{1}$ = $54\frac{1}{3}$

At the second track meet distance of the throw $D_{2}=54\frac{1}{2}$ feet

Expression that represents the improvement in the throw will be

D = $D_{2}-D_{1}$

D = $54\frac{1}{2}-51\frac{1}{3}$

D = $\frac{109}{2}-\frac{154}{3}$

D = $\frac{327-308}{6}$

D = $\frac{19}{6}$

D = $3\frac{1}{6}$ feet

George has 245 cards in his baseball card collection. Of these, 85 of the cards are pitchers. What percent of the cards are pitc

Licemer1 [7]

Answer:

17/49 or about 34.7%

Step-by-step explanation:

George has 85 cards out of 245 cards that are pitchers. Whever you hear "out of", it means to divide.

85/245 are pitchers.

you can simplify since 5 fits in both of those numbers

5*17=85

5*49=245

So, 17/49 or about 34.7%

Write the following as an expression: How much water do I need to add to l liters of pure alcohol to obtain a solution of 45% al

vredina [299]

Answer:

see below

Step-by-step explanation:

amount of water w

l liter of pure alcohol = 100% alcohol

solution is 45 % percent alcohol

total amount of fluid is w+l

(w+l)( .45) = l*.100

Distribute

.45w + .45 l = 1l

.45 w = 1l - .45l

.45 w = .55l

w = .55l / .45

w =11/9 l

How can you use number patterns to find the least common factor

Aleks04 [339]

Answer:

The correct answer is: 360.

Explanation:

First we can express 120 as follows:

2 * 2 * 2 * 3 * 5 = 120

You can get the above multiples as follows:

120/2 = 60

60/2 =30

30/2 = 15

15/3 = 5 (Since 15 cannot be divisible by 2, so we move to the next number)

5/5 = 1

Take all the terms in the denominator for 120, you would get: 2 * 2 * 2 * 3 * 5 --- (1)

Second we can express 360 as follows:

360/2 = 180

180/2 = 90

90/2 =45

45/3 = 15 (Since 45 cannot be divisible by 2, so we move to the next number)

15/3 = 5

5/5 = 1

Take all the terms in the denominator for 360, you would get: 2 * 2 * 2 * 3 * 3 * 5 --- (2)

Now in (1) and (2) consider the common terms once and multiple that with the remaining:

2*2*2*3*5 = Common between the two

3 = Remaining

Hence (2*2*2*3*5) * (3) = 360 = LCM (answer)
