The average weight of a basketball is 21 1/8 ounces. The average weight of a baseball is 5 2/8 ounces. How many more ounces does the basketball weigh?

Answers

Answer:

$15(7)/(8)\ ounces$

Step-by-step explanation:

step 1

Convert mixed number to an improper fraction

$21(1)/(8)\ ounces=21+(1)/(8)=(169)/(8)\ ounces$

$5(2)/(8)\ ounces=5+(2)/(8)=(42)/(8)\ ounces$

step 2

To find out how many more ounces does the basketball weigh, subtract the weight of a baseball from the weight f a basketball

$(169)/(8)\ ounces-(42)/(8)\ ounces=(127)/(8)\ ounces$

Convert to mixed number

$(127)/(8)\ ounces=(120)/(8)+(7)/(8)=15(7)/(8)\ ounces$

Answer:

$15(7)/(8) \ ounces$

Step-by-step explanation:

The questions tests for subtraction of fractions.

Start by converting the two fractions into improper numbers:

$21(1)/(8)=(169)/(8)\n5(2)/(8)=(42)/(8)$

Subtract the baseball weight from the basketball weight to obtain the additional weight in the latter.

More weight=>

$(169)/(8)-(42)/(8)\n=(127)/(8)\n=15(7)/(8)$

Answers

Answer:

1) Option C

2) Option C

3) Option B

4) Option B

5) Option A

Step-by-step explanation:

1) Identify the like terms ?

Terms are 9x, 10y, –9y, 10.

Like terms are those having same variable.

i.e. 10 y and -9y are like terms.

So, Option C is correct.

2) The term 25ab and which other term are like terms?

Option terms are 25,24a,5ba,10b

Like terms are those having same variable form.

i.e. 25ab and 5ba are like terms.

So, Option C is correct.

3) Combine like terms.

Expression $15w-28w$

combine like terms means adding and subtracting like terms with same variable.

i.e. $15w-28w=-13w$

So, Option B is correct.

4) Combine like terms.

Expression $9+18s- 7s$

combine like terms means adding and subtracting like terms with same variable.

i.e. $9+18s- 7s=9+11s$

So, Option B is correct.

5) Combine like terms.

Expression $(5)/(6)x-(2)/(3)x$

combine like terms means adding and subtracting like terms with same variable.

i.e. $(5)/(6)x-(2)/(3)x=(1)/(6)x$

So, Option A is correct.
