Multiplication and division: Identify the greater value

Let's solve exercise A:

$(4\times3)+(5\times12)=12+60=72$

Let's solve exercise B:

$(10\times3)+(7\times5)=30+35=65$

Let's solve exercise C:

$(7\times7)+(7\times3)=49+21=70$

Let's solve exercise D:

$(25\times2)+(15\times2)=50+30=80$

A:

$100-3\times20=100-(3\times20)=100-60=40$

B:

$10:5\times20=2\times20=40$

C:

$50-4\times3=50-(4\times3)=50-12=38$

D':

$20:4+10=(20:4)+10=5+10=15$

A:

$250-50:5=250-(50:5)=250-10=240$

B:

$100+30=130$

C:

$20\times4-7=(20\times4)-7=80-7=73$

D:

$10+4:2=10+(4:2)=10+2=12$

A:

$9\times7:3+3=(9\times7:3)+3=(63:3)+3=21+3=24$

B:

$20+4\times3=20+(4\times3)=20+12=32$

C:

$15\times4:6=60:6=10$

D:

$12-3+20=9+20=29$

Let's solve exercise A:

$(4\times11)+10=44+10=54$

Let's solve exercise B:

$(9\times3)+(9\times3)=27+27=54$

Let's solve exercise C:

$9+(8\times5)+7=9+40+7=49+7=56$

Let's solve exercise D:

$5+(5\times10)=5+50=55$
