Answer: 1 9/10

Step-by-step explanation:

1 1/2 +2/5.

First turn the first fraction into a fraction with no whole number= 3/2 Now find the common denominator which s 10. Multiply each denominator with a number to make it ten. What ever you do to the bottom you do to the top, so multiply the numerator as well.

3/2 x 5 = 15/10

2/5 x 2 = 4/10

Now add the 2 fractions together!

15/10 + 4/10 = 19/10

19/10 simplified is 1 9/10

The answer is 19/10 (1 9/10). You can find this by making 1 1/2 into an equivalent fraction or just adding it onto a calculator :)

Hope this helps!!

The price of a pair of shoes increases from $65 to $81. What is the percent increase to the

andriy [413]

Answer:

Percent increase = 25%

Step-by-step explanation:

Given that:

Old price of shoes = $65

New price of shoes = $81

Difference = 81 - 65

Difference = 16

Percent increase = $\frac{Difference}{Old\ price}*100$

Percent increase = $\frac{16}{65}*100$

Percent increase = 0.246 * 100

Percent increase = 24.6%

Rounding off to nearest whole number

Increase = 25%

Hence,

Percent increase = 25%

Jamal filled his gas tank and then use 7/16 of the tank for traveling to visit his grandfather. He then used 1/3 of the remainin

Lisa [10]

Answer:

$\frac{3}{8}$

Step-by-step explanation:

Let's tackle each statement at a time:

Jamal filled his gas tank of which he used $\frac{7}{16}$ .

We need to express the unit (a gas tank) in terms of fractions so that we can substract $1-\frac{7}{16}$ .

The denominator of the second term of our substraction is $16$ , so we can express the first term as $\frac{16}{16}$ . Now that we have the same denominator in both terms, we can proceed to define $16$ as a common denominator and rewrite the expression as: $\frac{16-7}{16}$ , which gives us a result of $\frac{9}{16}$ , which is what Jamal has left after visiting his grandfather. This expression cannot be simplified anymore.
