Answer:
3) 52 x 7= 50 x 7 + 2 x 7
Step-by-step explanation:
Just make sure you follow the rules of PEMDAS, solve left to right.
1) 52 x 7= 500 x 7 +2 x 7
52 x 7= 364
500 x 7= 3,500
2 x 7= 14
3,500 + 14= 3,514
364 does not equal 3,514!
So this one is not correct!
2) 52 x 7= 50 + 2 x 7
52 x 7= 364
2 x 7= 14
14 + 50= 64
364 does not equal 64!
So this one is not correct!
3) 52 x 7= 50 x 7 + 2 x 7
52 x 7= 364
50 x 7= 350
2 x 7= 14
350 + 14= 364
364= 364 so this one is correct!
Just to make sure:
4) 52 x 7= 50 x 7 + 2
52 x 7= 364
50 x 7= 350
350 + 2= 352
364 is not equal to 352!
So this one is not correct!
