70 and 4 if you add them. 80 and 6 if you subtract them. 37 and 2 if you multiply them. 148 and 2 if you divide them.
There are infinitely many possible answers: 1*70, 2*35, 3*(70/3), 4*17.5, 5*14, etc You can also include irrationals: sqrt(2)*sqrt(2450), etc And there is no reason to be restricted to two numbers: so 1*2*35, 1*2*3*(70/6) etc

70 = 2 * 5 * 7.
70*2

2 x 5 x 7 if you multiply them.
Each of these results in 70: 1 x 70, 2 x 35, 5 x 14, 7 x 10

The only way to do that is something like [ 2.5 x 28 ] or [ 3.5 x 20 ]. It can't be done with whole numbers. Here's why: -- The smallest possible 2-digit whole number is 10. -- So the smallest possible product of two 2-digit whole numbers is 100. -- So it's not possible to multiply two 2-digit whole numbers and get 70 .
The simplest answer is 1 and 70. There an infinte number of other pairs.
1 x 70 2 x 35 5 x 14 7 x 10 10 x 7
70 and 4 if you add them. 80 and 6 if you subtract them. 37 and 2 if you multiply them. 148 and 2 if you divide them.
