Your question is not clear. You want to multiply 1.4 added to one tenth. What are you multiplying it by? It takes a minimum of two numbers to perform a multiplication. If I add one tenth to 1.4 the sum is 1.5 and after that, I could multiply it by something if there was something to multiply it by.
One tenth of 140 is 14.
one tenth times 14 equals 1.4
14/100
(1/10) x 140 = 14
14/40 = 7/20
If 14 counters is half, you multiply it by 2 to get 28 counters, which is one.
14 inches rounded to the nearest tenth would be 14.0 inches.
1.4
There are infinitely many such numbers. Multiply 14 by any whole number and you have one.
1 is the tenth place in 14.
1,209,600 seconds in two weeks. Start out with 60 seconds in one minute. Multiply that by 60 because there is 60 minutes in one hour. Multiply that by 24 because there is 24 hours in one day. Then multiply that by 14 because there is 14 days in two weeks.
