The rules for converting fractions with denominators 10, 100, 1000, etc. into decimal fraction:
(i) Count the number of zeroes coming after 1 in the denominator.
(ii) Count an equal number of places in the numerator starting from the unit digit then place the decimal point to the left of the digit reached.
Let us consider some of the following examples;
1. Convert 819/100 to decimal.
Given, 819/100 This explanation will help you
Answer:
1,092 cm²
Step-by-step explanation:
Smaller box:
Length = 24 cm
Wrapping paper = 936 cm²
Bigger box:
Length= 28 cm
Wrapping paper = x cm²
Box : wrapping paper = 24 cm : 936 cm²
Box : wrapping paper = 28 cm : x cm²
Equate both ratios to find x
24 : 936 = 28 : x
24/936 = 28/x
Cross product
24 * x = 936 * 28
24x = 26,208
x = 26,208 / 24
x = 1,092 cm²
Bigger box:
Length= 28 cm
Wrapping paper = 1,092 cm²
Answer:
ten weeks
Step-by-step explanation:
62.50 multiped by 10 moves the decimal over 1 to the right which makes it 625 :)
Answer:
A rotation and a translation
or
rotation
Step-by-step explanation:
Again, we have to rotate to make the shape fit in, right?
But it wouldn't fit... Or will it? If you can take 2 guesses, you can try the rotation and a translation or the rotation.
Sorry, I'm also getting confused at some point :(!
