40 x .3
Remember: 0 . (tenths) (hundredths) (thousandths)
In this case (I missed it the first time) it's 30 hundredths, or 3 tenths
(4 x 10) x .3
Factoring out the 10 for the next step.
4 x (10 x .3)
Moving the 10 to the other side to make this easier to do in your head
4 x 3 = 12
To compare fractions 40/100 or 30/100 Since both have the same denominator of '100' , then just compare the numerators . 30 > 30 Hence it follows that 40/100 > 30/100 To compare decimals. 0.40 and 0.30 #1 ; drop the suffix zeroes , they are trivial Hence 0.4 & 0.3 #2 ; drop the decimal points Hence 04 & 03 #3 ; drop the prefix zeroes Hence 4 & 3 I think you will agree with me that 4 > 3 . Hence it follows that 0.40 > 0.30 NB This method is good for comparing any decimals.
To find out how many hundredths need to be added to 0.4 to make 0.7, first convert both numbers to hundredths. This means 0.4 is equal to 40 hundredths, and 0.7 is equal to 70 hundredths. The difference is 70 - 40 = 30. Therefore, 30 hundredths need to be added to 0.4 to make 0.7.
To show that 3 tenths is equal to 30 hundredths, you can convert 3 tenths into hundredths. Since 1 tenth is equivalent to 10 hundredths, you multiply 3 tenths by 10: (3 \times 10 = 30) hundredths. Therefore, 3 tenths (0.3) is equal to 30 hundredths (0.30).
To determine how many times 30 goes into 1200, you would divide 1200 by 30. The result of this division is 40, which means that 30 goes into 1200 40 times. Mathematically, this can be expressed as 1200 ÷ 30 = 40.
40 x 30 = 1200
It can be: 10*(3/100) = 30/100 which is 3/10 in its simplest form.
10*3/100 = 30/100.
2.3=(1.6 times 30)=23 tenths
Fraction ; 40/100 Decimal ; 0.40 However, in both cases. 40/100 can be reduced to 4/10 , and reduced again to 2/5 0.40 can have the suffix zero ignored as it is trivial , 0.4
2 times of 3 hundredths and 40 thousandths = 2 times of 3 hundredths and 4 hundredths = 2 times of 7 hundredths = 1 tenths and 4 hundredths = 0.14 Note: 1 thousandth = 0.001 (1/1000) 1 hundredth = 0.01 (1/100) 1 tenth = 0.1 (1/10)

It is 40%
