Explanation / Answer
1.) Estimate using the first digits to get: 70+60=130 Now take the adjustment by adding the bases of the second digits to get: 6+2=8 Adding them together you get: 130+8=138 2.) Estimate using the first digits to get: 80-30=50 Now take the adjustment by adding the bases of the second digits to get: 7-2=5 Adding them together you get: 50+5=55 3.) Estimate using the first digits to get: .6+.9+.4=1.9 Now take the adjustment by adding the bases of the second digits to get: .0+.0=0 Adding them together you get: 1.9+0=1.9
