Step-by-step explanation:
1st digit is 1 number (1)
2nd digit is (3,4,5) so it's 3 numbers
third digit is (6,7,8,9) is it's 4 numbers
last 7 digits is 10 (0,1,2,3,4,5,6,7,8,9)
multiply
1*3*4*10=120
so answer is 120 phone numbers
Answer:
the ratio is 10:12 and if you were to write it in a fraction you get 10/12 which can be simplified as 5/6
1925
1410+0515= 1925
The expression can be written as:
5(2) + 6(3) + 2(4).
if I'm wrong, please tell me
so since only 3 out of 11 went to visit then it is simple
since just 3 went and there were 11
3/11 of the students went
