Bonjour

A = 24/30 -4/30 + 1/30 = 21/30 = 7/10

B= 24/20 - 2/20 = 22/20 = 11/10

( priorité à la multiplication)

C= 24/64 -8/64 +1/64 = 17/64

A=4/5-2/15+1/30

=(24-4+1)/30

=21/30

=(21÷3)/(30÷3)

=7/10

B=6/5-2/5×1/4

=6/5-(2×1)/(5×4)

=6/5-2/20

=6/5-(2÷2)/(20÷2)

=6/5-1/10

=(12-1)/10

=11/10

C=3/8-2/16+1/64

=(24-8+1)/64

=17/64
