Consider, pls, this option (see the attachment) of 3 steps.
<span>2(3/2 + 5/3) - 1/3
3 + 10/3 - 1/3
3 + 9/3
3+3

1)
?×1/10=7.34
?=10×7.34
?=73.4
2)
8.64×?=0.864
?=0.864/8.64
?=864/8640
?=1/10=0.1
3)
?×100=69.4
?=69.4/100
?=694/1000
?=0.694
4)
790×?=79,000
?=79,000/790
?=100
5)
?×1/100=570
?=100×570
?=57000
6)
0.0064×?=6.4
?=6.4/0.0064
? =64000/64
?=1000
