If 7/12 is multiplied by a fraction less than 1 what would be the product

olga55 [171]

Answer:

<em>Examples below</em>

Step-by-step explanation:

We have the fraction

$\frac{7}{12}$

It's required to multiply it by any fraction less than 1. Let's select the following fractions. All of them are less than 1 because the numerator is less than the denominator:

$\frac{1}{7}$

$\frac{4}{5}$

$\frac{6}{35}$

The required products are:

$\frac{7}{12}\cdot \frac{1}{7}=\frac{7}{7*12}=\frac{1}{12}$

$\frac{7}{12}\cdot \frac{4}{5}=\frac{4*7}{12*5}=\frac{7}{15}$

$\frac{7}{12}\cdot \frac{6}{35}=\frac{6*7}{12*35}=\frac{1}{10}$

Even # --------- if it ends with 0, # of ways = 6*5*4 = 120 if not, 3 ways for ending digit, 5 ways for 1st digit, 5*4 for middle digits = 300
so total ways = 420
odd # --------- 4 ways of ending digit, 5 ways for 1st digit, 5*4 for middle digits = 400 ways
< 4000: ---------- 3 ways for starting digit, 6*5*4 ways for remaining digits = 360 ways
> 3000 & < 4000 ------------------------ 1 way for starting digit , 6*5*4 for remaining digits = 120 ways

Melons cost $20 pet Crate, and apples cost $8 per create. an order comes in for a total of 48 crates for $420. what was the numb

Alika [10]

Answer:

The number of melon was 3 and the number of apples was 45.

Step-by-step explanation:

1. Melons cost $20 per crate and apples cost $8 per create. If the total was 48 crates for $420, you can make the following system of equations, where $x$ is the number of melons and $y$ is the number of apples:

$\left \{ {{x+y=48} \atop {20x+8y=420}} \right.$

2. By applying the Method of substitution, you can solve for $y$ in the first equation and substitute it into the second one to find $x$ . Then, you can substitute the value of $x$ into the first equation to find $y$ :

$y=48-x$

$20x+8(48-x)=420\\20x+384-8x=420\\12x=36\\x=3$

$3+y=48\\y=45$
