son4ous [18]

Answer:

25 students

Step-by-step explanation:

we know that

44℅ of Mrs. Rutherford's class like chocolate ice cream

11 students like chocolate ice cream

11 students represent a 44℅ of Mrs. Rutherford's class

using proportion

Find out how many students represent a percentage of 100% (total students in the class)

$\frac{11}{44\%}=\frac{x}{100\%}\\\\x=11(100)/44\\\\x=25\ students$

What is 18 + 46 divided by 6

Amiraneli [1.4K]

18 + 46 = 64

See image

6s into 6 = 1
6s into 4 = 0    - carry the 4 over to the next space
6s into 40 = 6 remainder 4     -   carry the 4
6s into 40 = 6 remainder 4     -   carry the 4

4 will become repeatedly carried (an infinite number of times) so we call it a recurring number. This can be shown by a number (in this case 6) with a dot above it.
(18 + 46)/6 = 10.666... or 10.67
