Answer:
A): 22/5 = 4 2/5 in mixed fraction. 22/5 = 4.4 in decimal. B): 0.875
Step-by-step explanation:
Since you can't divide 7/8 it will turn into decimal. If you use calculator, it will be decimal. Basically in order to do long division, you would need to drop down zeros like add zeros if the divisor and dividend don't equal. You keep adding zeros until it's equal. IF it is more likely to be continuous, then you would need to add a repetend on the last digit. For example, 3/1 you can know it would be 1.333333 and so on. Example of how to do it:
A and D
456/2=228
456/3=152
1548/2=774
1548/3=516
hope this helps!
Answer:
45 positive numbers have the sum of their digits equal to 8
Step-by-step explanation:
given data
number = 1 to 999
sum n = 8
to find out
positive numbers
solution
we will choose number by this formula
(n+1) (n+2) / 2
here n is 8
so put this value we get number that
positive numbers = (n+1) (n+2) / 2
positive numbers = (8+1) (8+2) / 2
positive numbers = 90 / 2
so 45 positive numbers have the sum of their digits equal to 8
Answer:
10, 19 and 57
Step-by-step explanation:
let the first number be a, the second be b and the third be c
a+b+c=86
the second number is 9 less than the first
a=b+9------i
b=a-9
the third number is 3 times the first
c=3a------ii
a=c/3
therefore
b+9=c/3
c=3(b+9)
b+9+b+3(b+9)=86
b+9+b+3b+27=86
collecting like terms
5b=86-(27+9)
5b=86-36
5b=50
therefore
b=10
recall i to solve for a
a=b+9
a=10+9
a=19
recall ii to solve for c
c=3a
c=3*19
c=57
