Надо сделать так, чтобы знаменатель был одинаковый.
146/10-1/9=(146/10)×9-(1/9)×10=(1314/90)-(10/90)=
=1304/90=14 44/90

My mum loved Australia. She adored anything connected to Australia. Kangaroos, koala bears, Uluru, sun, sea and surfing, she loved all that. She even supported the Aussie cricket team and we are British! She also liked to watch Australian soaps: ‘Neighbours’, ‘Home and Away’, ‘the Young Doctors’. She dreamed to go and visit the country and my dad agreed. My sister Ginny and I were also ready to go: I must admit, I like Australia, too! We saved up for three years for our trip and finally, last summer, we travelled. Luckily, that was before the coronavirus pandemic! We hurried to Sydney and stopped in the town centre in a nice hotel. We stayed there for five days. We looked at the Opera House of course, but we didn’t go to an opera. We had a trip out to see Uluru. It was magnificent, a brilliant sight. We wanted to see some of the wildlife, so we booked a trip to Edith Falls National Park. The scenery was wonderful and it was great to see koala bears! Finally, we visited Northern Queensland and enjoyed some time at a fantastic beach. We didn’t surf, but we jumped into the sea from the rock. It was brilliant. We noticed the people were very friendly; everyone greeted us with a ‘G’day’ and the food was really delicious. My mum was so happy! Now, she wants to go and live there, but my dad says ‘No!’ – well, at least for the time being!
