Step-by-step explanation:

distance walked by him = 1/ 3 miles

time taken in doing so = 3/ 4 hrs.

$speed \: acquired \: by \: him \: = \frac{distance}{time}$

$= \frac{ \frac{1}{3} }{ \frac{3}{4} } \\ = \frac{ 1}{3} \times \frac{4}{3} \\ = \frac{4}{9} \: miles \: hr^{ - 1}$

Grant spent 2.50,$4.00,$4.25, and $3.25?On breakfast one week.The next week he spent $6 more in total for the 4 breakfasts than

masha68 [24]

We have been given that Grant spent $2.50, $4.00, $4.25, and $3.25 on breakfast in one week. The next week he spent $6 more in total for the 4 breakfasts than the week before. We are asked to find increase in the mean of second week.

Since Grant spent $6 more than last week, we will divide 6 by 4 to get how much mean of second week breakfast expenditures increased with respect to first week expenditures.

$\text{Mean increase in second week breakfast expenditure}=\frac{6}{4}$

$\text{Mean increase in second week breakfast expenditure}=1.5$

Therefore, mean of second week breakfast expenditure will be $1.5 more than first week.

What is the value of x 1/5 = 25/x

Mama L [17]

First getting x as a numerator rather than a denominator. Then grouping like terms by moving 5 from the left side to the right. Work below:
$\frac{1}{5} = \frac{25}{x} \\ \frac{1}{5}*x = \frac{25}{x}*x\\ \frac{1}{5}x = 25\\\frac{1}{5}x * 5 = 25*5\\x=125$

Add 1/4 + 5/14 +6/7 Simplify the answer and write it as a mixed number.

Answer:

$\frac{41}{28}$ = $1\frac{13}{28}$

Step-by-step explanation:

In order to add fractions, the denominators must all be the same value (the lowest common denominator). The lowest common denominator is the smallest value that all of the given denominators (in this case, the denominators are 4, 14, and 7) can divide into.

Here, the smallest number that all three of the given denominators can perfectly divide into is 28:

28 ÷ 4 = 7

28 ÷ 14 = 2

28 ÷ 7 = 4

Therefore, our lowest common denominator is 28.

The next step is to change our numerators to match our lowest common denominator. To do this, we have to multiply the numerator by the same value that we would need to multiple the denominator by in order to get our lowest common denominator.

For our first term of 1/4, we need to multiply our denominator (4) by 7 in order to get our lowest common denominator of 28. So, we need to also multiply our numerator by 7:

$\frac{1}{4}$ × $\frac{7}{7}$ = $\frac{7}{28}$
