First, let me do the Mathematical part of that, and then I shall explain the theory behind it.
Mathematical part:
We are going to multiply 513 with 46. So the two partial products that we are going to choose are 40 and 6.
Multiply 513 with 6 first.
513
x46
--------------------------
18 (as 6*3 = 18)
60 (as 6*10 = 60; In 513, the digit at tenths place is 1, so 1*10=10)
3000 (as 6*500 = 3000; In 513, 5 is at hundredth place, so 5*100=500)
120 (as 40*3 = 120; since 4 is at the tenth place, so 4*10=40)
400 (as 40*10 = 400)
20000 (as 40*500 = 20000)
--------------------------
23598 (Add all of them)
Theory:
As you can see above that we have chosen the two partial products individually which are 6 and 40. Since 4 in 46 is in tenth place, we have to consider it 40 (since 4*10 = 40). One by one, we first multiply 6 with 513. Then we move to the tenth place, and multiply 513 with 40. At the end, we have added all the results we found after multiplication.
Check: If we check the multiplication result by using the calculator, we would get the same result (23598).
Another Method (instant):
513 * (40+6) = (513*40) + (513*6) = 23598.
50p-40p+25-p
9p+25 is the answer.
Answer:
103.69
Step-by-step explanation:
5% of 98.75 is about 4.94. So if you were to do money, it'd be 98.75 + 4.94, which equals about 103.69.
They each got 4 dollars because all the $ added up will be 16 and it divided by the 4 kids 16 •|• 4= 4
Find the quotient 4.2 ÷7=> 4.2 is our dividend which is a decimal number. 4 as the whole number and 2 is the decimal number.=> 7 is our divisor that will be use to divide with 4.3Let's now start solving:=> 4.2 / 7 = 0.6<span>Thus the quotient of the given data is 0.6 which is also a decimal number same as the divisor.</span>
