Five cats each ate 1/4 cup of canned food . How much food did they eat altogether?

Sauron [17]

We have FIVE cats that each ate 1/4 cup of canned food.

Then, the five of them together ate:

5 times 1/4 cup This in mathematical expression is a profduct of an integer value (5) times the fraction (1/4) which we know how to multiply based on the problems we solved a few minutes ago:

5 * 1/4 = 5/1 * 1/4 = (5 * 1) / (1 * 4) = 5/4 cups

This answer can also be written as a MIXED number given that 5/4 is an IMPROPER fraction (a fraction with numerator larger than the denominator)

5/4 = 1 1/4

Not sure what answer your teacher would prefer. It depends on whether he/she wants you to use fractions or mixed numbers.

Three sevenths of a children's choir are boys. If there are 12 boys in the choir, how many children, c, total are in the choir?

ruslelena [56]

Answer:

Here c represents the total number of children in choir.

As per the statement:

Total number of boys in choir = 12

It is also given that: Three sevenths of a children's choir are boys.

⇒ Total number of boys = $\frac{3}{7} c$

$12 = \frac{3}{7}c$

By cross multiply we have;

84 = 3c

Divide both sides by 3 we have;

c = 28

Therefore, the total number of children in choir is 28 children

solve for x and y ,32base x+51base y and 23base x +42 base y =710. ,number bases interms of simultaneous equation

In-s [12.5K]

Answer:

Step-by-step explanation:

32base x means $3x + 2$

Similarly, 32base x+51base y equals to $3x + 2 + 5y + 1 = 3x + 5y + 3$

and 23base x +42 base y means $2x + 3 + 4y + 2 = 2x + 4y + 5$

As per the given condition, $3x + 5y + 3 = 2x + 4y + 5\\x + y = 2$

Putting, $y = 2 - x$ in $2x + 4y + 5 = 710$ , we get

$2x + 4y = 705\\2x + 4(2 - x) = 705\\8 - 2x = 705\\4 - x = 352.5\\x = -348.5$

$y = 2 - x = 2 - (-348.5) = 2 + 348.5 = 350.5$
