70x4=280
Multiplication by an integer is the same as repeated addition.
There are a few ways to determine if a multiplication fact is correct:Repeated addition: since multiplication is simply repeated addition at its base, you can reaffirm a multiplication fact by repeatedly adding the number you're multiplying. With the basic multiplication facts (i.e. times tables), this is possibly the best option.Division: Since it's simply the reverse of multiplication, then you can just reverse the process to confirm it.Using multiple methods: There are multiple ways to do multiplication than just the usual long multiplication done in school, such as lattice multiplication, and Ayurvedic multiplication (just to name the two I know). You can use these to confirm a multiplication.
One-fifth of 280 = 280/5 = 56Therefore: Two-fifths of 280 = 56*2 = 112

70x4=280
70 multiplied by 4 equals 280. This can be calculated by adding 70 four times, or by using the multiplication operation to find the product of 70 and 4. Multiplication is a mathematical operation that combines two numbers to find their total value. In this case, 70 times 4 results in 280.
Multiplication by an integer is the same as repeated addition.
If one event can occur in "m" ways and a second can occur independently of the first in "n" ways, then the two events can occur in "mn" ways.
There are infinitely many possible answers. 280 * 0.1 is one option.
In most mathematical circumstances, the word "of" signifies multiplication. 135 x 280 = 37,800 I can't help feeling there's something missing. Here's a guess: 135 percent of 280 is 378.

196 ======= 70 is 25% of 280 in my humble opinion.
A dot stands for multiplication. Ways to show multiplication: 10a 10 x a 10(a) 10 *dot* a
The need of arithmetic shifting is useful in different ways. But is used mostly in multiplication or division and powering it by two.
