Step-by-step explanation:
100% divided by 4 is 25%
25 books were 1/4 of the books total.
the other 3/4 would be 75%
they og ordered 100 books
Answer:
1/5
Step-by-step explanation:
For Monday
The fraction of homework Chain completed =
40% of her homework
= 40% = 40/100
= 2/5
For Tuesday
The amount of home work left =
= 1 - 2/5
3/5
The fraction of homework Chain completed on Tuesday = 2/3
= 2/3 Of 3/5
= 2/3 × 3/5
= 2/5
Let the total complete homework be represented by 1
Hence:
The Fractional part of her homework left for her to complete after Tuesday =
1 - (2/5 + 2/5)
Lowest common denominator is 5
= 1 - (2 + 2/5)
= 1 - (4 /5)
= 1/5
Answer:
384 m³
Step-by-step explanation:
Let the dimension of box a be l,b, and h.
ATQ,
lbh = 48 .....(1)
If we double the dimension of box A, we get box B whose new dimensions will be 2l,2b and 2h.
Let V be the volume of box B.
V = (2l)(2b)(2h)
V = 8(lbh)
= 8(48) [from equation (1)]
= 384 m³
Hence, the volume of the box B is 384 m³.
Answer:
For the given expression: 
Step-by-step explanation:
Here, the given expression in statement form is given as:
5 X minus Y equals 6 + negative 2 X plus Y = 8
Now, converting the given statement mathematically, we get:
5X - Y = 6 + (-2X) + Y = 8
Now, considering first and the last terms,we get:
5 X - Y = 8 .... (1)
and , considering second and the last terms,we get:
6 + (-2X) + Y = 8 or, -2X + Y = 2 ......... (2)
Adding (1) and (2) , we get:
5 X - Y - 2 X + Y = 8 + 2
or, 3 X = 10
or, X = 10/3 = 3.34
Now, 5X - Y = 8
or, 
Hence, for the given expression:

Step-by-step explanation:
x(x-3)=0
x=0 or (x-3) =0
x= 0 or x =3
